&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-size: 12.0pt; line-height: 115%;&quot;&gt;A pirâmide alimentar é um instrumento,
sob a forma gráfica, que tem como objetivo orientar as pessoas para uma dieta
mais saudável. É um guia alimentar geral que demonstra como deve ser a
alimentação diária para uma população saudável, acima de 2 anos de idade.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-size: 12.0pt; line-height: 115%;&quot;&gt;Cada parte
da pirâmide representa um grupo de alimentos e o número de porções recomendadas
diariamente. Na alimentação diária devemos incluir sempre todos os grupos
recomendados para garantir os nutrientes que o nosso organismo necessita. Os
alimentos que precisam ser consumidos numa quantidade maior estão na base da
pirâmide e os que precisam ser consumidos em menor quantidade estão no topo da
pirâmide.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-size: 12.0pt; line-height: 115%;&quot;&gt;Para
sabermos o número correto de porções diárias a serem ingeridas de cada grupo de
alimentos, é necessário observar as calorias diárias que cada indivíduo
necessita.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-size: 12.0pt; line-height: 115%;&quot;&gt;Portanto, é
necessário que o profissional da área de nutrição planeje o programa alimentar,
pois este varia conforme sexo, peso, idade, altura e necessidades individuais.
Em média, a maioria dos indivíduos necessita de, pelo menos, um número mínimo
de porções dentro das variações recomendadas.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;

Segundo a capacidade de voar, as aves podem ser divididas em carinatas e ratitas.&lt;/div&gt;

Possuem músculos peitorais desenvolvidos, responsáveis pelo batimento das asas. Muitas podem voar, outras fazem apenas voos curtos, como a galinha. Algumas aves como os pinguins, sofreram modificações em suas asas, que as tornaram aptas apenas para a natação.&lt;/div&gt;
&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;

&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;
A pele das aves é queratinizada, seca e impermeável. Algumas possuem&amp;nbsp;&lt;span style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-weight: 700; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;&quot;&gt;glândulas uropigianas&lt;/span&gt;​, situadas sobre a região posterior do corpo, acima da cauda, que secretam um óleo.&lt;/div&gt;
&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;
Os patos, por exemplo, viram a cabeça até a cauda e esfregam o bico no restante do corpo, impermeabilizando as penas antes de entrarem nas lagoas, o que facilita a sua flutuação.&lt;/div&gt;
&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;
Outra característica das aves é o canto, gerado por um órgão fonador a&amp;nbsp;&lt;span style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-weight: 700; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;&quot;&gt;siringe&lt;/span&gt;. O canto pode servir como elemento de comunicação, envolvendo atração sexual, advertência, demarcação de território etc.&lt;/div&gt;

As aves são animais ovíparos, ou seja, produzem ovos. A casca é formada por carbonato de cálcio e por ser porosa permite a troca gasosa entre o embrião e o ambiente. A cloaca é órgão responsável pela postura dos ovos.&lt;/div&gt;
&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;

No interior do ovo, há membranas protetoras e reservas alimentares na forma de gema e clara.&lt;/div&gt;

O sistema circulatório das aves apresenta um coração com quatro câmaras: dois átrios e dois ventrículos. Funciona como duas bombas distintas, onde as câmaras direitas impulsionam sangue não oxigenado e as da esquerda, sangue oxigenado.&lt;/div&gt;

&lt;div style=&quot;background-color: white; color: #222222; font-family: Tahoma, Verdana, Arial, sans-serif; font-size: 12px; margin-bottom: 10px; margin-top: 10px; padding: 0px; text-align: justify;&quot;&gt;
A&amp;nbsp;&lt;strong&gt;PIRÂMIDE ALIMENTAR&lt;/strong&gt;&amp;nbsp;é uma guia da boa alimentação. Ela divide em oito grupos os alimentos existentes, criados para auxiliar as pessoas sobre o que elas devem comer. Mostra, então, de forma gráfica a quantidade de cada tipo de alimento que devemos consumir diariamente.&lt;/div&gt;
&lt;div style=&quot;background-color: white; color: #222222; font-family: Tahoma, Verdana, Arial, sans-serif; font-size: 12px; margin-bottom: 10px; margin-top: 10px; padding: 0px; text-align: justify;&quot;&gt;
Ela tem como objetivo principal mostrar que uma&amp;nbsp;&lt;a href=&quot;http://alimentacao-saudavel.info/&quot; rel=&quot;nofollow&quot; style=&quot;color: #f5b400; outline: 0px; text-decoration-line: none;&quot; target=&quot;_blank&quot;&gt;alimentação saudável&lt;/a&gt;&amp;nbsp;deve ser variada e moderada e a partir desse tipo de regime alimentar, conseguiremos diminuir doenças como a obesidade e a carência de nutrientes.&lt;/div&gt;
&lt;div style=&quot;background-color: white; color: #222222; font-family: Tahoma, Verdana, Arial, sans-serif; font-size: 12px; margin-bottom: 10px; margin-top: 10px; padding: 0px; text-align: justify;&quot;&gt;
A pirâmide tradicional é dividida em seis&amp;nbsp;&lt;strong&gt;grupos alimentares&lt;/strong&gt;, que estão repartidos em quatros degraus. Na base, se encontram os carboidratos, importantes fontes de energia; acima, estão os vegetais e frutas; logo depois, as proteínas de carnes e grãos, além dos laticínios e por último, estão os lipídeos e açúcares, que devem ser consumidos com moderação.&lt;/div&gt;

&lt;div style=&quot;background-color: white; color: #222222; font-family: Tahoma, Verdana, Arial, sans-serif; font-size: 12px; margin-bottom: 10px; margin-top: 10px; padding: 0px; text-align: justify;&quot;&gt;
Apesar de ter um conceito único, existem diversos tipos de pirâmide alimentar adaptadas de acordo com os hábitos alimentares de alguns países, respeitando culturas e a disponibilidade de alimentos daquela região. Há, ainda, aquelas feitas a partir de alguns estudos e pesquisas.&lt;/div&gt;
&lt;div style=&quot;background-color: white; color: #222222; font-family: Tahoma, Verdana, Arial, sans-serif; font-size: 12px; margin-bottom: 10px; margin-top: 10px; padding: 0px; text-align: justify;&quot;&gt;
As mais conhecidas são as:&lt;/div&gt;
&lt;ul style=&quot;background-color: white; color: #222222; font-family: Tahoma, Verdana, Arial, sans-serif; font-size: 12px; list-style-type: square; margin: 10px 0px 5px; padding: 0px;&quot;&gt;

A boca é a porta de entrada dos alimentos no tubo digestivo. Corresponde a uma cavidade forrada por mucosa, onde os alimentos são umidificados pela saliva, produzida pelas glândulas salivares.&lt;/div&gt;

A faringe é um tubo muscular membranoso, que se comunica com a boca, através do istmo da garganta e na outra extremidade com o esôfago. Para chegar ao esôfago, o alimento, depois de mastigado, percorre toda a faringe, que é um canal comum, para o sistema digestório e o sistema respiratório.&lt;/div&gt;

A gastrina é produzida no próprio estômago no momento que moléculas de proteínas dos alimentos entram em contato com a parede do órgão. Assim, a pepsina quebra as moléculas grandes de proteína e as transforma em moléculas menores. Estas são as&amp;nbsp;&lt;span style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-weight: 700; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;&quot;&gt;proteoses&lt;/span&gt;&amp;nbsp;e&amp;nbsp;&lt;span style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-weight: 700; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;&quot;&gt;peptonas&lt;/span&gt;.&lt;/div&gt;

Assim, o duodeno é a primeira porção do intestino delgado a receber o quimo que vem do estômago, que ainda está muito ácido, sendo irritante à mucosa duodenal.&lt;/div&gt;

Assim, em pouco tempo, a “papa” alimentar do duodeno, vai-se tornando alcalina e gerando condições necessárias para ocorrer a digestão intra-intestinal.&lt;/div&gt;

No ceco, a primeira porção do intestino grosso, os resíduos alimentares, já constituindo o “bolo fecal”, passam ao cólon ascendente, depois ao transverso e em seguida ao descendente. Nesta porção, o bolo fecal permanece estagnado por muitas horas, preenchendo as porções da curva sigmoide e do reto.&lt;/div&gt;
&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;
O reto é a parte final do intestino grosso, que termina com o canal anal e o&amp;nbsp;&lt;span style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-weight: 700; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;&quot;&gt;ânus&lt;/span&gt;, por onde são eliminadas as fezes.&lt;/div&gt;
&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;
Para facilitar a passagem do bolo fecal, as glândulas da mucosa do intestino grosso secretam muco a fim de lubrificar o bolo fecal, facilitando seu trânsito e sua eliminação.&lt;/div&gt;
&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;

Sendo portanto importante incluir as fibras na alimentação para auxiliar a formação das fezes.&lt;/div&gt;

&lt;span style=&quot;color: #222222; font-family: Arial; font-size: 13.0pt;&quot;&gt;Muitos mamíferos apresentam comportamentos complexos associados à reprodução, como os comportamentos de corte. A fecundação é interna. O macho tem dois testículos, dois epidídimos, dois canais deferentes e um pênis. A fêmea possui útero, vagina, genitália externa e dois ovários e ovidutos. A maioria é vivípara e amniota (exceto os monotremados).&lt;/span&gt;&lt;/div&gt;

&lt;b&gt;&lt;span style=&quot;color: windowtext; font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Sistema
Respiratório&lt;/span&gt;&lt;/b&gt;&lt;/h1&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;




O sistema respiratório é o conjunto dos órgãos responsáveis, basicamente, pela &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;absorção
do oxigênio&lt;/span&gt;&lt;/strong&gt; &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;do ar&lt;/span&gt;&lt;/strong&gt; pelo organismo e da&lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;
eliminação&lt;/span&gt;&lt;/strong&gt; &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;do gás carbônico&lt;/span&gt;&lt;/strong&gt; retirado das
células.&lt;/span&gt;&lt;br /&gt;


&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;O sistema respiratório é formado pelas &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;vias
respiratórias&lt;/span&gt;&lt;/strong&gt; e pelos &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;pulmões&lt;/span&gt;&lt;/strong&gt;. Os órgãos que
compõem as vias respiratórias são: &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;cavidades&lt;/span&gt;&lt;/strong&gt; &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;nasais&lt;/span&gt;&lt;/strong&gt;,
&lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;faringe&lt;/span&gt;&lt;/strong&gt;, &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;laringe&lt;/span&gt;&lt;/strong&gt;, &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;traqueia&lt;/span&gt;&lt;/strong&gt;
e &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;brônquios&lt;/span&gt;&lt;/strong&gt;.&lt;/span&gt;&lt;br /&gt;


&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;&lt;/span&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;&lt;/span&gt;&lt;br /&gt;


&lt;h2&gt;
&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Órgãos do Sistema Respiratório&lt;/span&gt;&lt;/h2&gt;
&lt;h3&gt;
&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Cavidades Nasais&lt;/span&gt;&lt;/h3&gt;
&lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;Cavidades nasais&lt;/span&gt;&lt;/strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt; são dois
condutos paralelos revestidos de mucosa, separados por um septo cartilaginoso,
que começam nas narinas e terminam na faringe.&lt;/span&gt;&lt;br /&gt;

pelos que atuam como filtro de ar&lt;/span&gt;&lt;/strong&gt;, retendo impurezas e germes,
garantindo que o ar chegue limpo aos pulmões.&lt;/span&gt;&lt;br /&gt;


&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;A membrana que reveste as cavidades nasais
contém células produtoras de muco que umidifica o ar. É rica em vasos
sanguíneos que aquecem o ar que entra no nariz.&lt;/span&gt;&lt;br /&gt;


&lt;h3&gt;
&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Faringe&lt;/span&gt;&lt;/h3&gt;

alimentos quanto para o ar, portanto, faz parte do sistema respiratório e do
sistema digestório.&lt;/span&gt;&lt;br /&gt;


&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Em sua extremidade superior se comunica com
as cavidades nasais e com a boca, na extremidade inferior se comunica com a
laringe e o esôfago. Suas paredes são musculosas e revestidas de mucosa.&lt;/span&gt;&lt;br /&gt;


&lt;h3&gt;
&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Laringe&lt;/span&gt;&lt;/h3&gt;

que liga a faringe à traqueia. Na parte superior da laringe, está a epiglote, a
válvula que se fecha durante a deglutição. A laringe é também o órgão principal
da fala. Nela estão localizadas as cordas vocais.&lt;/span&gt;&lt;br /&gt;


&lt;h3&gt;
&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Traqueia&lt;/span&gt;&lt;/h3&gt;

&lt;/span&gt;&lt;/strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;é um tubo situado abaixo da
laringe e formado por quinze a vinte anéis cartilaginosos que a mantêm aberta.
É revestida por uma membrana mucosa, e nela o ar é aquecido, umidificado e
filtrado.&lt;/span&gt;&lt;br /&gt;


&lt;h3&gt;
&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Brônquios&lt;/span&gt;&lt;/h3&gt;

&lt;/span&gt;&lt;/strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;são duas ramificações da traqueia
formadas também por anéis cartilaginosos. Cada brônquio penetra em um dos
pulmões e divide-se em diversos ramos menores, que se distribuem por todo o
órgão formando os bronquíolos. Cada brônquio se ramifica subdividindo-se várias
vezes, formando a árvore brônquica.&lt;/span&gt;&lt;br /&gt;


&lt;h3&gt;
&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Pulmões&lt;/span&gt;&lt;/h3&gt;
&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;O sistema respiratório é composto por dois &lt;a data-saferedirecturl=&quot;https://www.google.com/url?hl=pt-BR&amp;amp;q=https://www.todamateria.com.br/pulmao/&amp;amp;source=gmail&amp;amp;ust=1508800614934000&amp;amp;usg=AFQjCNGe7JaLdL5v1np15SHLNyHQeubhuA&quot; href=&quot;https://www.todamateria.com.br/pulmao/&quot; target=&quot;_blank&quot;&gt;&lt;strong&gt;&lt;span style=&quot;color: windowtext; font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal; text-decoration: none;&quot;&gt;pulmões&lt;/span&gt;&lt;/strong&gt;&lt;/a&gt;, órgãos
esponjosos, situados na caixa torácica.&lt;/span&gt;&lt;br /&gt;


&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Cada pulmão é envolvido por uma membrana
dupla, chamada &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;pleura&lt;/span&gt;&lt;/strong&gt;. Internamente, cada
pulmão apresenta cerca de 200 milhões de estruturas muito pequenas, em forma de
cacho de uva e que se enche de ar, chamados de &lt;a data-saferedirecturl=&quot;https://www.google.com/url?hl=pt-BR&amp;amp;q=https://www.todamateria.com.br/alveolos-pulmonares/&amp;amp;source=gmail&amp;amp;ust=1508800614934000&amp;amp;usg=AFQjCNFhG7q3W1YR84LN8OJ2Ra_aK6g__g&quot; href=&quot;https://www.todamateria.com.br/alveolos-pulmonares/&quot; target=&quot;_blank&quot;&gt;&lt;span style=&quot;color: windowtext; text-decoration: none;&quot;&gt;alvéolos

&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Cada alvéolo recebe ramificações de um
bronquíolo. Nos alvéolos realizam-se as &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;trocas gasosas&lt;/span&gt;&lt;/strong&gt;, denominada &lt;a data-saferedirecturl=&quot;https://www.google.com/url?hl=pt-BR&amp;amp;q=https://www.todamateria.com.br/hematose/&amp;amp;source=gmail&amp;amp;ust=1508800614934000&amp;amp;usg=AFQjCNG0REHcr8sgbcTjgPrXotgiT1xN9Q&quot; href=&quot;https://www.todamateria.com.br/hematose/&quot; target=&quot;_blank&quot;&gt;&lt;span style=&quot;color: windowtext; text-decoration: none;&quot;&gt;hematose&lt;/span&gt;&lt;/a&gt;, entre o ambiente

&lt;b&gt;&lt;span style=&quot;color: windowtext; font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Sistema
Circulatório&lt;/span&gt;&lt;/b&gt;&lt;/h1&gt;
&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;O &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;Sistema circulatório&lt;/span&gt;&lt;/strong&gt; ou &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;cardiovascular&lt;/span&gt;&lt;/strong&gt;,
formado pelo &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;coração&lt;/span&gt;&lt;/strong&gt; e &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;vasos sanguíneos&lt;/span&gt;&lt;/strong&gt;, é
responsável pelo transporte de nutrientes e oxigênio para as diversas partes do
corpo.&lt;/span&gt;&lt;br /&gt;


&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;A partir disso, a circulação sanguínea
corresponde a todo o percurso do sistema circulatório que o sangue realiza no
corpo humano, de modo que no percurso completo, o sangue passa duas vezes pelo
coração.&lt;/span&gt;&lt;br /&gt;


&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Esses circuitos são chamados de &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;pequena&lt;/span&gt;&lt;/strong&gt;
&lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;circulação&lt;/span&gt;&lt;/strong&gt; e &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;grande&lt;/span&gt;&lt;/strong&gt; &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;circulação&lt;/span&gt;&lt;/strong&gt;&lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;.&lt;/span&gt;&lt;/strong&gt;&lt;/span&gt;&lt;br /&gt;


&lt;h2&gt;
&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Pequena Circulação&lt;/span&gt;&lt;/h2&gt;
&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;A &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;Pequena Circulação&lt;/span&gt;&lt;/strong&gt; ou &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;Circulação
Pulmonar&lt;/span&gt;&lt;/strong&gt;&lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt; &lt;/span&gt;&lt;/strong&gt;é
o caminho que o sangue percorre do &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;coração aos pulmões&lt;/span&gt;&lt;/strong&gt;, e dos
pulmões ao coração. Assim, o sangue venoso é bombeado do &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;ventrículo
direito&lt;/span&gt;&lt;/strong&gt; para a &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;artéria pulmonar,&lt;/span&gt;&lt;/strong&gt; que se
ramifica de maneira que uma segue para o pulmão direito e outra para o pulmão
esquerdo.&lt;/span&gt;&lt;br /&gt;


&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Já nos pulmões, o sangue presente nos
capilares dos alvéolos libera o gás carbônico e absorve o gás oxigênio. Por
fim, o sangue arterial (oxigenado) é levado dos pulmões ao coração, através das&lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt; &lt;/span&gt;&lt;/strong&gt;&lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;veias
pulmonares&lt;/span&gt;&lt;/strong&gt;, que se conectam no &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;átrio esquerdo&lt;/span&gt;&lt;/strong&gt;&lt;b&gt;.&lt;/b&gt;&lt;/span&gt;&lt;br /&gt;

Circulação&lt;span&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;/span&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;A Grande Circulação ou &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;Circulação
Sistêmica&lt;/span&gt;&lt;/strong&gt;&lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt; &lt;/span&gt;&lt;/strong&gt;é
o caminho do sangue, que sai do &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;coração até as demais células do corpo&lt;/span&gt;&lt;/strong&gt;
e vice-versa.&lt;/span&gt;&lt;br /&gt;


&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;No coração, o sangue arterial vindo dos
pulmões, é bombeado do átrio esquerdo para o &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;ventrículo esquerdo&lt;/span&gt;&lt;/strong&gt;&lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;. &lt;/span&gt;&lt;/strong&gt;Do ventrículo passa para a
artéria &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;aorta&lt;/span&gt;&lt;/strong&gt;&lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;, &lt;/span&gt;&lt;/strong&gt;que
é responsável por transportar esse sangue para os diversos tecidos do corpo.&lt;/span&gt;&lt;br /&gt;


&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Assim, quando esse sangue oxigenado chega aos
tecidos, os vasos capilares refazem as trocas dos gases: absorvem o gás
oxigênio e liberam o gás carbônico, tornando o sangue venoso.&lt;/span&gt;&lt;br /&gt;


&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Por fim, o sangue venoso faz o caminho de
volta ao coração e chega ao &lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;átrio direito&lt;/span&gt;&lt;/strong&gt; pelas&lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt; &lt;/span&gt;&lt;/strong&gt;&lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;veias
cavas superiores&lt;/span&gt;&lt;/strong&gt;&lt;b&gt; &lt;/b&gt;&lt;strong&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif; font-weight: normal;&quot;&gt;e
inferiores&lt;/span&gt;&lt;/strong&gt;&lt;b&gt;,&lt;/b&gt;
completando o sistema circulatório.&lt;/span&gt;&lt;br /&gt;

&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;O coração é um &lt;span&gt;órgão muscular&lt;/span&gt;, que se localiza na
caixa torácica, entre os pulmões. Funciona como uma bomba dupla, de modo que o
lado esquerdo bombeia o sangue arterial para as diversas partes do corpo,
enquanto o lado direito bombeia o sangue venoso para os pulmões.&lt;/span&gt;&lt;/div&gt;
&lt;div align=&quot;left&quot; class=&quot;MsoNormal&quot; style=&quot;line-height: normal; text-align: left; text-indent: 0cm;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;O coração
funciona impulsionando o sangue por meio de dois movimentos: contração,
denominado sístole e relaxamento, denominado diástole. As principais estruturas
são:&lt;/span&gt;&lt;/div&gt;
&lt;ul type=&quot;disc&quot;&gt;
&lt;li class=&quot;MsoNormal&quot; style=&quot;line-height: normal; text-align: left;&quot;&gt;&lt;b&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Pericárdio&lt;/span&gt;&lt;/b&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;: membrana que reveste o

&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;As artérias são
&lt;span&gt;vasos do sistema circulatório&lt;/span&gt;,
que saem do coração e transportam o sangue para as outras partes do corpo. A
parede da artéria é espessa, formada de tecido muscular e elástico, que suporta
a pressão do sangue.&lt;/span&gt;&lt;/div&gt;
&lt;div align=&quot;left&quot; class=&quot;MsoNormal&quot; style=&quot;line-height: normal; text-align: left; text-indent: 0cm;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;O sangue
venoso, rico em gás carbônico, é bombeado do coração para os pulmões através
das artérias pulmonares. Enquanto o sangue arterial, rico em gás oxigênio, é
bombeado do coração para os tecidos do corpo através da artéria aorta.&lt;/span&gt;&lt;/div&gt;
&lt;div align=&quot;left&quot; class=&quot;MsoNormal&quot; style=&quot;line-height: normal; text-align: left; text-indent: 0cm;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;As artérias se
ramificam pelo corpo, ficam mais finas, formam as arteríolas, que se ramificam
ainda mais, originando os capilares.&lt;/span&gt;&lt;/div&gt;

&lt;div align=&quot;left&quot; class=&quot;MsoNormal&quot; style=&quot;line-height: normal; text-align: left; text-indent: 0cm;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;As veias são &lt;span&gt;vasos do sistema circulatório&lt;/span&gt;, que
transportam o sangue de volta dos tecidos do corpo para o coração. Suas paredes
são mais finas que as artérias. A maior parte das veias transporta o sangue
venoso, ou seja, rico em gás carbônico. Contudo, as veias pulmonares
transportam o sangue arterial, oxigenado, dos pulmões para o coração.&lt;/span&gt;&lt;/div&gt;
&lt;div align=&quot;left&quot; class=&quot;MsoNormal&quot; style=&quot;line-height: normal; text-align: left; text-indent: 0cm;&quot;&gt;
&lt;b&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Capilares&lt;/span&gt;&lt;/b&gt;&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div align=&quot;left&quot; class=&quot;MsoNormal&quot; style=&quot;line-height: normal; text-align: left; text-indent: 0cm;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Os capilares
são &lt;span&gt;ramificações microscópicas de&lt;/span&gt;
&lt;span&gt;artérias&lt;/span&gt; e &lt;span&gt;veias&lt;/span&gt; do sistema circulatório. Suas
paredes apresentam apenas uma camada de células, que permitem a troca de
substâncias entre o sangue e as células. Os capilares se ligam às veias,
levando o sangue de volta para o coração.&lt;/span&gt;&lt;/div&gt;
&lt;div align=&quot;left&quot; class=&quot;MsoNormal&quot; style=&quot;line-height: normal; text-align: left; text-indent: 0cm;&quot;&gt;
&lt;span style=&quot;font-family: &amp;quot;Calibri&amp;quot;,sans-serif;&quot;&gt;Pelo corpo de
uma pessoa adulta circula, em média, seis litros de sangue, numa ampla rede de
vasos sanguíneos, bombeados pelo coração.&lt;/span&gt;&lt;/div&gt;

&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;
O corpo dos répteis é formado por cabeça, pescoço, tronco e cauda.&lt;/div&gt;
&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;
Eles possuem dois pares de membros locomotores, cada um com cinco dedos acabados em garras e pernas reduzidas em alguns lagartos, mas ausentes em outros, como as cobras.&lt;/div&gt;
&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;
Eles podem ser animais rastejantes ou nadadores, como as tartarugas marinhas que possuem patas em forma de remos.&lt;/div&gt;
&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;
A pele é ressecada e resistente, coberta por escamas de origem epidérmica, o que a torna queratinizada e praticamente impermeável.&lt;/div&gt;
&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;
Porém, alguns animais, como as tartarugas e jabutis, também podem apresentar placas ósseas de origem dérmica.&lt;/div&gt;
&lt;h3 style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; margin: 0px; outline: 0px; padding: 1em 0px 0.5em; vertical-align: baseline;&quot;&gt;
Temperatura corporal&lt;/h3&gt;
&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;
Os répteis são animais pecilotérmicos, ou seja, são incapazes de manter a sua temperatura corporal constante. Assim, eles necessitam do calor do ambiente para regulação da temperatura corporal.&lt;/div&gt;
&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;
Essa condição limita sua localização dos seus habitats aos trópicos e subtrópicos do planeta, onde as temperaturas favorecem o seu metabolismo. Por isso, não encontramos répteis na Antártica.&lt;/div&gt;
&lt;h3 style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; margin: 0px; outline: 0px; padding: 1em 0px 0.5em; vertical-align: baseline;&quot;&gt;
Reprodução&lt;/h3&gt;
&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px 0px; vertical-align: baseline;&quot;&gt;

Apresentam fecundação interna, onde o macho introduz os espermatozoides no interior do corpo da fêmea.&lt;/div&gt;
&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;
O desenvolvimento do embrião ocorre dentro dos ovos, os quais são revestidos por cascas córneas ou calcárias.&lt;/div&gt;
&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;
Essa característica protege o embrião da dessecação, importante para a conquista do ambiente terrestre.&lt;/div&gt;
&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;
O ovo apresenta os seguintes anexos embrionários: âmnio, cório, saco vitelino e alantoide.&lt;/div&gt;
&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;
Quando os filhotes nascem assemelham-se aos adultos, pois o desenvolvimento é direto.&lt;/div&gt;
&lt;h3 style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; margin: 0px; outline: 0px; padding: 1em 0px 0.5em; vertical-align: baseline;&quot;&gt;

Alguns répteis, como o jacaré e a matamatá, são animais predadores e ocupam o topo da cadeia alimentar.&lt;/div&gt;
&lt;h3 style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; margin: 0px; outline: 0px; padding: 1em 0px 0.5em; vertical-align: baseline;&quot;&gt;

O órgão olfativo dos répteis lhes permite sentir o gosto e o cheiro, sendo que a maioria dos répteis é capaz de ouvir sons.&lt;/div&gt;
&lt;div style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-family: &amp;quot;Droid Serif&amp;quot;, serif; line-height: 1.625; max-width: 685px; outline: 0px; padding: 0.7em 0px; vertical-align: baseline;&quot;&gt;
A visão não é privilegiada, mas os olhos possuem pálpebras e membrana nictitante para protegê-los quando submersos.&lt;/div&gt;

Os anfíbios vivem em água doce, entretanto há duas exceções: a rã comedora de caranguejos, que vive em ambiente marinho, e a rã-aguadeira, do Deserto Australiano. As&amp;nbsp;&lt;span style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-weight: 700; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;&quot;&gt;principais características&lt;/span&gt;&amp;nbsp;são:&lt;/div&gt;

Digestão&lt;/h2&gt;

Embora possam ter duas fileiras de dentes, os anfíbios não mastigam suas presas. A língua bem desenvolvida é usada na captura de insetos, que é envolto em um muco que o lubrifica, facilitando sua passagem no tubo digestivo.&lt;/div&gt;

Os anfíbios não ingerem água, ela é obtida através da pele, que também executa a troca gasosa entre o sangue e o ar. É rica em glândulas e está sempre úmida. Os sapos possuem um par de glândulas chamadas&amp;nbsp;&lt;span style=&quot;background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: 0px 0px; background-repeat: initial; background-size: initial; border: 0px; box-sizing: border-box; font-weight: 700; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;&quot;&gt;paratóides&lt;/span&gt;, que contêm veneno e constituem defesa contra os predadores.&lt;/div&gt;

Os pulmões são formados por dois sacos, sem divisão interna. As narinas abrem-se na cavidade da boca. Enquanto estão na fase larval, aquática, respiram por meio de brânquias.&lt;/div&gt;

Os embriões se desenvolvem em forma de larvas, que passam pela metamorfose, originando os adultos.&lt;/div&gt;
&lt;/li&gt;

Acredita-se que os peixes tenham surgido por volta de 45 milhões de anos atrás.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;background-color: white; font-family: &amp;quot;verdana&amp;quot; , &amp;quot;arial&amp;quot; , &amp;quot;helvetica&amp;quot; , sans-serif; font-size: 11px; text-align: justify;&quot;&gt;&lt;br /&gt;&lt;/span&gt;

Os peixes ocupam as águas salgadas dos&amp;nbsp;&lt;strong&gt;mares&lt;/strong&gt;&amp;nbsp;e&amp;nbsp;&lt;strong&gt;oceanos&lt;/strong&gt;&amp;nbsp;e as águas doces dos&amp;nbsp;&lt;strong&gt;rios&lt;/strong&gt;,&amp;nbsp;&lt;strong&gt;lagos&lt;/strong&gt;&amp;nbsp;e&amp;nbsp;&lt;strong&gt;açudes&lt;/strong&gt;. Nesse grupo, existem cerca de 24 mil espécies, das quais mais da metade vive em água salgada. O tamanho médio dos peixes pode variar de um centímetro a até cerca de 18 metros.&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;margin-bottom: 10px; text-align: justify;&quot;&gt;
Provavelmente, foram os primeiros vertebrados a surgir na Terra, e eram pequenos, sem mandíbula, tinham coluna vertebral cartilaginosa e uma carapaça revestindo seus corpos. Na evolução, houve uma série de adaptações que representaram aos peixes melhores condições de sobrevivência em seu habitat -&amp;nbsp;&lt;span class=&quot;verde&quot; style=&quot;color: #337337;&quot;&gt;&lt;strong&gt;não ter couraça pesada, ser nadadores velozes, ter mandíbulas e poder morder&lt;/strong&gt;&lt;/span&gt;.&lt;/div&gt;
&lt;/td&gt;&lt;/tr&gt;
&lt;/tbody&gt;&lt;/table&gt;
&lt;div align=&quot;justify&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px;&quot;&gt;
&lt;span class=&quot;texto&quot;&gt;Antes limitados à filtração de partículas nutritivas suspensas na água ou depositadas no fundo e sendo presas de alguns tipos de invertebrados, os peixes tornaram-se também eficientes predadores.&lt;/span&gt;&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px; text-align: justify;&quot;&gt;
Desde que surgiram, já ocupavam com sucesso os ambientes aquáticos salgado e doce, e continuam assim até hoje.&lt;/div&gt;
&lt;div align=&quot;center&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px; text-align: justify;&quot;&gt;

Características que favorecem a vida na água&lt;/div&gt;
&lt;div style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px;&quot;&gt;
Os peixes apresentam várias características que favorecem o desempenho de suas atividades no ambiente em que vivem. Entre elas, destacam-se:&lt;/div&gt;
&lt;ul style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px;&quot;&gt;
&lt;li class=&quot;texto&quot;&gt;corpo com formato, em geral, hidrodinâmico, isto é,&amp;nbsp;&lt;strong class=&quot;laranja&quot; style=&quot;color: #ec9536;&quot;&gt;achatado lateralmente e alongado&lt;/strong&gt;, o que favorece seu deslocamento na água;&lt;/li&gt;
&lt;li class=&quot;texto&quot;&gt;presença de&amp;nbsp;&lt;strong class=&quot;vermelho&quot; style=&quot;color: red;&quot;&gt;nadadeiras&lt;/strong&gt;, estruturas de locomoção que, quanto à localização, podem ser peitorais, ventrais, dorsais, caudais e anais;&lt;/li&gt;
&lt;li class=&quot;texto&quot;&gt;corpo geralmente recoberto por&amp;nbsp;&lt;strong class=&quot;verde&quot; style=&quot;color: #337337;&quot;&gt;escamas lisas&lt;/strong&gt;, cuja organização diminui o atrito com a água enquanto o animal se desloca; além disso , a pele é dotada de&amp;nbsp;&lt;strong class=&quot;azulEscuro&quot; style=&quot;color: navy;&quot;&gt;glândulas produtoras de muco&lt;/strong&gt;, o que também contribui para diminuir o atrito com a água;&lt;/li&gt;
&lt;li class=&quot;texto&quot;&gt;&lt;span class=&quot;azul&quot; style=&quot;color: blue;&quot;&gt;&lt;strong&gt;musculatura do tronco segmentada&lt;/strong&gt;&lt;/span&gt;, o que permite a realização de movimentos ondulatórios.&lt;/li&gt;
&lt;li class=&quot;texto&quot;&gt;&lt;div align=&quot;center&quot; class=&quot;titulo2&quot; style=&quot;font-family: Arial, Verdana, Helvetica, sans-serif; font-size: 14px; font-weight: bold; margin-bottom: 10px;&quot;&gt;
A temperatura corporal&lt;/div&gt;
&lt;div align=&quot;justify&quot; style=&quot;margin-bottom: 10px;&quot;&gt;
Os peixes são animais&amp;nbsp;&lt;strong class=&quot;vermelho&quot; style=&quot;color: red;&quot;&gt;pecilotérmicos&lt;/strong&gt;. Isso significa que a temperatura do seu corpo varia de acordo com a do ambiente. A temperatura do corpo dos peixes em geral mantém-se mais ou menos próxima à temperatura ambiental.&lt;/div&gt;
&lt;div class=&quot;titulo2&quot; style=&quot;font-family: Arial, Verdana, Helvetica, sans-serif; font-size: 14px; font-weight: bold; margin-bottom: 10px;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div align=&quot;center&quot; class=&quot;titulo2&quot; style=&quot;font-family: Arial, Verdana, Helvetica, sans-serif; font-size: 14px; font-weight: bold; margin-bottom: 10px;&quot;&gt;
Respiração e circulação de sangue&lt;/div&gt;
&lt;div align=&quot;justify&quot; style=&quot;margin-bottom: 10px;&quot;&gt;
A maioria dos peixes respira por meio de&amp;nbsp;&lt;strong&gt;brânquias&lt;/strong&gt;, também conhecidas como guelras. A água entra continuamente pela boca do peixe, banha as brânquias e sai pelas aberturas existentes de cada lado da cabeça.&lt;/div&gt;
&lt;div align=&quot;justify&quot; style=&quot;margin-bottom: 10px;&quot;&gt;
Nas brânquias, onde existem muitos vasos sanguíneos, o gás oxigênio dissolvido na água passa para o sangue. Ao mesmo tempo, o gás carbônico que se forma no organismo do animal e que está no sangue passa para a água, sendo eliminado do corpo.&lt;/div&gt;
&lt;div align=&quot;justify&quot; style=&quot;margin-bottom: 10px;&quot;&gt;
O coração dos peixes tem&lt;strong&gt;&amp;nbsp;duas cavidades um átrio e um ventrículo&lt;/strong&gt;&amp;nbsp;- e por ele circula apenas sangue não-oxigenado. Depois de passar pelo coração, o sangue não oxigenado vai para uma artéria e dai para as brânquias, onde recebe gás oxigênio. A seguir, esse sangue, agora oxigenado, é distribuído para todos os órgãos do corpo do animal.&lt;/div&gt;
&lt;div align=&quot;justify&quot; style=&quot;margin-bottom: 10px;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;div align=&quot;center&quot; class=&quot;titulo2&quot; style=&quot;background-color: white; font-family: Arial, Verdana, Helvetica, sans-serif; font-size: 14px; font-weight: bold; margin-bottom: 10px;&quot;&gt;
Alimentação e digestão&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px;&quot;&gt;
Alguns peixes são&amp;nbsp;&lt;strong&gt;herbívoros&lt;/strong&gt;, alimentando-se principalmente de algas. Outros são&lt;strong&gt;&amp;nbsp;carnívoros&lt;/strong&gt;, e alimentam-se de outros peixes e de animais diversos, como moluscos e crustáceos.&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px;&quot;&gt;
Nas zonas abissais - os grandes abismos oceânicos, destituídos de luz -, onde os seres fotossintetizantes não sobrevivem, há muitos peixes&amp;nbsp;&lt;strong&gt;detritívoros&lt;/strong&gt;, que se alimentam de restos orgânicos oriundos da superfície iluminada, e também peixes carnívoros.&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px;&quot;&gt;
O sistema digestório dos peixes é constituído de boca, faringe, esôfago, estômago e intestino, além de glândulas anexas, como o fígado e o pâncreas.&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div align=&quot;center&quot; class=&quot;titulo2&quot; style=&quot;background-color: white; font-family: Arial, Verdana, Helvetica, sans-serif; font-size: 14px; font-weight: bold; margin-bottom: 10px;&quot;&gt;
Os sentidos&lt;/div&gt;
&lt;div class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px; text-align: start;&quot;&gt;
Os peixes têm vários órgãos dos sentidos&lt;/div&gt;
&lt;ul style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; text-align: start;&quot;&gt;
&lt;li class=&quot;texto&quot;&gt;&lt;span class=&quot;laranja&quot; style=&quot;color: #ec9536;&quot;&gt;&lt;strong&gt;Bolsa olfatória&lt;/strong&gt;&lt;/span&gt;&lt;strong&gt;&amp;nbsp;-&lt;/strong&gt;&amp;nbsp;São formadas por células localizadas nas narinas e associadas à percepção de cheiros das substâncias dissolvidas na água. O sentido do olfato dos peixes é geralmente muito aguçado. O tubarão, por exemplo, pode &quot;farejar&quot; sangue fresco a dezenas de metros de distância.&lt;/li&gt;
&lt;li class=&quot;texto&quot;&gt;&lt;span class=&quot;verde&quot; style=&quot;color: #337337;&quot;&gt;&lt;strong&gt;Olhos&lt;/strong&gt;&lt;/span&gt;&lt;strong&gt;&amp;nbsp;-&lt;/strong&gt;&amp;nbsp;Permitem formar imagens nítidas a curta distância. A distâncias maiores, percebem apenas objetos em movimento na superfície da água. Alguns peixes têm percepção das cores e outros não. Os tubarões e as raias (também conhecidas como arraias), por exemplo, não distinguem cores. Os olhos são geralmente grandes e não possuem pálpebras nem glândulas lacrimais.&lt;/li&gt;
&lt;li class=&quot;texto&quot;&gt;&lt;span class=&quot;azul&quot; style=&quot;color: blue;&quot;&gt;&lt;strong&gt;Linha lateral&lt;/strong&gt;&lt;/span&gt;&lt;strong&gt;&amp;nbsp;-&lt;/strong&gt;&amp;nbsp;É formada por uma fileira de poros situada de cada lado do corpo, com ramificações na cabeça. Os poros comunicam-se com um canal localizado sob as escamas, no qual existem células sensoriais. Por meio das células sensoriais, o peixe percebe as diferenças de pressão da água, que aumenta gradativamente com a profundidade. Percebe também correntes e vibrações na água, detectando a presença de uma presa, de um predador ou os movimentos de outros peixes que estão nadando ao seu lado, o que é muito importante para as viagens em cardumes. Percebe, ainda, a direção dos movimentos da água, o que facilita sua locomoção na escuridão ou em águas turvas.&lt;/li&gt;
&lt;/ul&gt;
&lt;/div&gt;

&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-size: 12.0pt; line-height: 115%;&quot;&gt;Os moluscos
são animais de corpo mole, geralmente envolto por uma concha. A concha é
presente em ostras, mariscos, caracol e caramujo. Em alguns, como a lula, a
concha é interna e em outros, é ausente, como no polvo. As conchas são
importantes para proteger o corpo mole dos moluscos e evitar a perda de água. Os
moluscos vivem em ambiente aquático marinho ou de água doce e no meio terrestre
úmido.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-size: 12.0pt; line-height: 115%;&quot;&gt;Esses
animais apresentam o corpo dividido em: cabeça,
pé e massa visceral. Na cabeça são encontrados os órgãos dos sentidos. O
pé é responsável pelos movimentos e, em alguns animais, como o polvo, pode ser
substituído pelos tentáculos. A massa visceral é onde se encontram todos os
órgãos.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-size: 12.0pt; line-height: 115%;&quot;&gt;Os moluscos
possuem um sistema digestivo completo, com boca e ânus. O alimento é conduzido
pelo tubo digestivo, onde sofre a ação de enzimas. Os nutrientes são absorvidos
e distribuídos pelo corpo por meio do sangue. Os cefalópodes e gastrópodes
apresentam a rádula, uma espécie
de língua com dentes afiados, usada para raspar os alimentos.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-size: 12.0pt; line-height: 115%;&quot;&gt;O sistema
circulatório distribui os nutrientes e oxigênio dos sistemas digestivo e
respiratório. O sistema excretor retira resíduos metabólicos e os elimina. O
sistema circulatório é aberto, e o coração situa-se dorsalmente na massa visceral.
As contrações do coração enviam para o corpo, o sangue que flui para os vasos e
depois por lacunas situadas entre os tecidos.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;

A maioria dos moluscos
apresenta sexos separados, com exceção dos bivalves que são hermafroditas. Na
fecundação externa, os machos liberam os espermatozóides e as fêmeas liberam os
óvulos diretamente na água, onde os dois gametas se encontram. No caso da
fecundação interna, os espermatozoides são liberados dentro do corpo da fêmea.&lt;b&gt;&lt;o:p&gt;&lt;/o:p&gt;&lt;/b&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-size: 12.0pt; line-height: 115%;&quot;&gt;&amp;nbsp;São os
anelídeos que possuem como principal característica a existência de muitas
cerdas (parapódios) nas regiões laterais do corpo. A maioria dos poliquetas
vive no mar e algumas espécies têm as águas doces como habitat. Os poliquetas,
ao contrário dos oligoquetos, não possuem clitelo. Grande parte destes
anelídeos é de sexos separados. Existem fases larvais durante o processo de
desenvolvimento.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-size: 12.0pt; line-height: 115%;&quot;&gt;São os
anelídeos que possuem poucas cerdas no corpo. Algumas espécies são marinhas,
enquanto outras vivem na terra. Os oligoquetos são hermafroditas, podendo se
reproduzir de forma assexuada ou sexuada. A fecundação destes anelídeos é
cruzada, apresentando desenvolvimento direto. Os oligoquetos possuem na
epiderme o clitelo, cuja função é fabricar um casulo que guarda os ovos
fecundados durante a reprodução.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;

Os&amp;nbsp;&lt;b&gt;vertebrados&lt;/b&gt;&amp;nbsp;(do latim&amp;nbsp;&lt;i&gt;vertebratus&lt;/i&gt;, com vértebras) constituem um subfilo de animais cordados, compreendendo os ágnatos, peixes, anfíbios, répteis, aves e mamíferos. Caracterizam-se pela presença de&lt;span class=&quot;texto&quot;&gt;&lt;strong&gt;coluna vertebral&lt;/strong&gt;&lt;/span&gt;&amp;nbsp;segmentada e de&amp;nbsp;&lt;span class=&quot;texto&quot;&gt;&lt;strong&gt;crânio&lt;/strong&gt;&lt;/span&gt;&amp;nbsp;que lhes protege o cérebro.&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px;&quot;&gt;
Outras características adicionais são a presença de um sistema muscular geralmente simétrico – a&amp;nbsp;&lt;strong&gt;simetria bilateral&lt;/strong&gt;&amp;nbsp;é também uma característica dos vertebrados – e de um&amp;nbsp;&lt;strong&gt;sistema nervoso central&lt;/strong&gt;, formado pelo cérebro e pela medula espinhal localizados dentro da parte central do esqueleto (crânio e coluna vertebral).&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px;&quot;&gt;
Os primeiros vestígios dos vertebrados foram encontrados no período Siluriano (há 444 a 409 milhões de anos).&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px;&quot;&gt;

Características e Classificação dos Cordados&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px; margin-left: 0pt; text-indent: 0pt;&quot;&gt;
Todo cordado apresenta, pelo menos em alguma fase de sua existência:&lt;/div&gt;
&lt;ul style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px;&quot;&gt;
&lt;li class=&quot;texto&quot;&gt;&lt;strong class=&quot;azulEscuro&quot; style=&quot;color: navy;&quot;&gt;notocorda&lt;/strong&gt;, situada ao longo do eixo mediano dorsal do animal;&lt;/li&gt;
&lt;li class=&quot;texto&quot;&gt;um&amp;nbsp;&lt;strong class=&quot;laranja&quot; style=&quot;color: #ec9536;&quot;&gt;tubo nervoso&amp;nbsp;&lt;/strong&gt;localizado dorsalmente, acima da notocorda;&lt;/li&gt;
&lt;li class=&quot;texto&quot;&gt;&lt;strong class=&quot;vermelho&quot; style=&quot;color: red;&quot;&gt;fendas situadas&lt;/strong&gt;&amp;nbsp;bilateralmente na faringe;&lt;/li&gt;
&lt;li class=&quot;texto&quot;&gt;&lt;strong class=&quot;verde&quot; style=&quot;color: #337337;&quot;&gt;cauda pós-anal&lt;/strong&gt;, primariamente importante para a propulsão no meio aquático. Dela, apenas um vestígio - o cóccix, formado de um conjunto de vértebras pequenas no fim da coluna vertebral - restou nos seres humanos.&lt;/li&gt;
&lt;/ul&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px;&quot;&gt;
Nos grupos de invertebrados, as características morfológicas sempre foram definidas a partir do estudo de animais adultos. Nos cordados, no entanto, a caracterização do grupo deve ser procurada na fase embrionária. É nessa fase que todo o cordado apresenta as quatro características típicas do grupo: notocorda, tubo nervoso dorsal, fendas na faringe e cauda pós-anal.&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px;&quot;&gt;
Na fase adulta dos vertebrados mais complexos, essas estruturas ou desaparecem, como é o caso da notocorda e das fendas na faringe, ou sofrem consideráveis modificação, como é o caso do tubo nervoso, que passa por uma grande expansão, levando à diferenciação do encéfalo e da medula espinhal.&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px; margin-left: 0pt; text-indent: 0pt;&quot;&gt;
Uma classificação satisfatória dos cordados consiste em agrupá-los em três subfilos:&amp;nbsp;&lt;strong&gt;Urochordata, Cephalochordata e Vertebrata&lt;/strong&gt;&amp;nbsp;(ou Craniata). Os urocordados e os cefalocordados também são conhecidos como protocordados. Os protocordados não possuem crânio, nem cartilagem, tampouco ossos.&lt;/div&gt;
&lt;table border=&quot;0&quot; style=&quot;background-color: white; color: black; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; width: 606px;&quot;&gt;&lt;tbody&gt;

&lt;span class=&quot;texto&quot; style=&quot;margin-left: 0pt; text-indent: 0pt;&quot;&gt;Entre os vertebrados, os mais primitivos são os que possuem boca circular, não-dotada de mandíbulas. Estes compõem os grupos dos vertebrados amandibulados ou&lt;strong&gt;&amp;nbsp;ágnatos&lt;/strong&gt;&amp;nbsp;(do grego,&amp;nbsp;&lt;em&gt;a&lt;/em&gt;&amp;nbsp;= ausência de +&amp;nbsp;&lt;em&gt;gnathos&lt;/em&gt;&amp;nbsp;= maxila).&lt;/span&gt;&lt;/div&gt;
&lt;div align=&quot;justify&quot; style=&quot;margin-bottom: 10px;&quot;&gt;
&lt;span class=&quot;texto&quot; style=&quot;margin-left: 0pt; text-indent: 0pt;&quot;&gt;Por possuírem boca circular, também são conhecidos por ciclostomados (do grego,&amp;nbsp;&lt;em&gt;kúklos&lt;/em&gt;&amp;nbsp;= circulo +&amp;nbsp;&lt;em&gt;stoma&lt;/em&gt;&amp;nbsp;= boca). Os exemplares mais conhecidos atualmente são as lampreias.&lt;/span&gt;&lt;/div&gt;
&lt;div align=&quot;justify&quot; style=&quot;margin-bottom: 10px;&quot;&gt;
&lt;span class=&quot;texto&quot; style=&quot;margin-left: 0pt; text-indent: 0pt;&quot;&gt;Nos vertebrados mais complexos, a boca possui mandíbulas. São os&amp;nbsp;&lt;strong&gt;gnatostomados&lt;/strong&gt;, que incluem dois grupos: o dos peixes - que, por sua vez, contém a classe dos peixes cartilaginosos e dos peixes ósseos - e o dos tetrápodos (do grego,&amp;nbsp;&lt;em&gt;tetra&lt;/em&gt;&amp;nbsp;=quatro +&amp;nbsp;&lt;em&gt;podos&lt;/em&gt;&amp;nbsp;= pés), assim chamados por possuírem apêndices locomotores pares (inclui os anfibios, répteis, aves e mamíferos).&lt;/span&gt;&lt;/div&gt;
&lt;/td&gt;&lt;/tr&gt;
&lt;/tbody&gt;&lt;/table&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px; margin-left: 0pt; text-indent: 0pt;&quot;&gt;

Subfilo Urochordata&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px; margin-left: 0pt; text-indent: 0pt;&quot;&gt;
Também conhecidos como tunicados, nome que se deve ao envoltório do corpo, uma túnica espessa, de cuja composição química participa a tunicina, uma substância semelhante à celulose.&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px; margin-left: 0pt; text-indent: 0pt;&quot;&gt;
Os representantes mais conhecidos desse grupo são as&amp;nbsp;&lt;strong&gt;ascídias&lt;/strong&gt;, cordados marinhos que podem viver isolados ou formando colônias. Uma das formas isoladas muito encontrada nas praias brasileiras lembra, no adulto, um pedaço de piche de aproximadamente 8 cm de altura, preso por uma de suas extremidades ao substrato (rochas, cascos de navios etc.)&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px; margin-left: 0pt; text-indent: 0pt;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;table align=&quot;center&quot; border=&quot;0&quot; style=&quot;background-color: white; color: black; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; width: 456px;&quot;&gt;&lt;tbody&gt;

&lt;/tbody&gt;&lt;/table&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px; margin-left: 0pt; text-indent: 0pt;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px; margin-left: 0pt; text-indent: 0pt;&quot;&gt;
Observe na figura acima as duas aberturas. O maior é o sifão inalante, permite o ingresso de água trazendo oxigênio e partículas alimentares que ficam retidas na faringe perfurada por fendas. Por batimento ciliar, o alimento é levado da faringe ao estômago. A água que entra no animal, sai pelo segundo sifão, o sifão exalante, levando os produtos de excreção. São, portanto, animais filtradores.&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px; margin-left: 0pt; text-indent: 0pt;&quot;&gt;
As ascídias são hermafroditas. A fecundação é externa. Os gametas são levados pela água através do sifão exalante. Os ovos fertilizados geram larvas, de pequeno tamanho. A larva, mostrada acima, parece muito com a larva de sapo (girino) o que sugere forte parentesco com os vertebrados.&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;texto&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px; margin-left: 0pt; text-indent: 0pt;&quot;&gt;
A larva das ascídias é livre natante. Os adultos são fixos. Na larva dos tunicados, a notocorda restringe-se à cauda.&lt;/div&gt;

Apenas os Arthropoda apresentam maior diversidade.

DIGESTÃO:Os nematódeos são os primeiros animais a apresentarem&amp;nbsp;&lt;strong&gt;sistema digestório completo,&lt;/strong&gt;&amp;nbsp;ou seja, possuem boca e ânus.&lt;/div&gt;
&lt;div align=&quot;justify&quot; style=&quot;background-color: white; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; margin-bottom: 10px;&quot;&gt;
A boca possui lábios ao redor. Esses lábios possuem papilas sensoriais, dentes ou placas cortantes seguidas de uma faringe musculosa que efetua sucção do alimento, bombeando para o intestino. Os parasitas alimentam-se de produtos pré-digeridos pelo hospedeiro, mas há também espécies fitófagas e carnívoras.&lt;/div&gt;

Ou seja, a fêmea é diferente do macho. Normalmente os machos são menores e sua porção posterior é afilada e curva, para facilitar a cópula. A fecundação é cruzada e o desenvolvimento é indireto.&lt;/span&gt;&lt;/div&gt;

&lt;br /&gt;
Os cnidários são os primeiros animais a apresentarem uma cavidade digestiva no corpo.&lt;br /&gt;
A presença de uma cavidade digestiva permitiu aos animais ingerirem porções maiores de alimento, pois nela o alimento pode ser digerido e reduzido a pedaços menores, antes de ser absorvido pelas células.&lt;br /&gt;
&lt;br /&gt;
Com base no aspecto externo do corpo, os cnidários apresentam simetria radial. Eles são os primeiros animais na escala evolutiva a apresentarem tecidos verdadeiros, embora ainda não cheguem a formar órgãos.&lt;br /&gt;
&lt;br /&gt;
No filo cnidária existem basicamente dois tipos morfológicos de indivíduos: as medusas, que são natantes e os pólipos, que são sésseis.&lt;br /&gt;
Tanto o pólipo como a medusa apresentam uma boca que se abre na cavidade gastrovascular, mas não possuem ânus. O alimento ingerido pela boca, cai na cavidade gastrovascular, onde é parcialmente digerido e distribuido.&lt;br /&gt;
pós a fase extracelular da digestão, o alimento é absorvido pelas células que revestem a cavidade gastrovascular, completando a digestão.&lt;br /&gt;
&lt;br /&gt;
A digestão é portanto, em parte extracelular e em parte intracelular. Os restos não-aproveitáveis são liberados pela boca. Na região oral, estão os tentáculos, que participam na captura de alimentos.&lt;br /&gt;
&lt;br /&gt;
As camadas de célula que ocorrem nos cnidários são: a epiderme, que reveste o corpo externamente, e a gastroderme, que reveste a cavidade gastrovascular. Entre a epiderme e a gastroderme existe uma camada gelatinosa denominada mesogléia.&lt;br /&gt;

reprodução das planárias é assexuada.Com isso divide-se em duas
partes e cada uma delas gera um novo indivíduo. A planária ao se
alimentar distende sua faringe sobre o alimento e inicia a ingestão.
Transcorrida a digestão, os nutrientes são distribuídos pelo corpo
por meio de intestino ramificado. &lt;/span&gt;&lt;/span&gt;

&lt;span style=&quot;box-sizing: border-box; font-weight: 700;&quot;&gt;A importância dos fungos&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Os fungos são importantes, principalmente, para a decomposição da matéria orgânica. Sem os decompositores não haveria reciclagem de nutrientes, da qual depende a vida no planeta. Também existem fungos mutualísticos, que estabelecem relações benéficas com certos organismos.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Além de sua importância na decomposição da matéria orgânica, os fungos também são importantes para o mercado financeiro. São utilizados para a produção de certos medicamentos, inseticidas e desinfetantes, também são usados para fins culinários, como por exemplo o Shitaki e Shimeji.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
&lt;span style=&quot;box-sizing: border-box; font-weight: 700;&quot;&gt;Nutrição&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Todos os fungos são heterótrofos por absorção, ou seja, são incapazes de produzir seu próprio alimento, e sua digestão é feita fora do corpo, quando o fungo lança enzimas que degradam moléculas orgânicas complexas em moléculas mais simples, para serem absorvidas. Quanto aos modos de vida, os fungos podem ser:&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
• Decompositores: são os fungos saprófagos, que promovem a reciclagem de matéria orgânica, sendo que a maioria deles vive no solo, obtendo nutrientes de seres mortos. Estes também são responsáveis pelo apodrecimento de alimentos e outros materiais, como a madeira.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
• Parasitas: se alimentos de substâncias que retiram de organismos vivos, prejudicando-os e muitas vezes ocasionando sua morte. Muitas doenças são causadas por esses fungos.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
• Mutualísticos: são fungos que se associam a organismos, estabelecendo uma relação de beneficio mútuo. Podemos citar os liquens e as micorrizas como exemplos dessas associações.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
• Predadores: são fungos que obtêm alguns ou a maioria dos seus nutrientes por aprisionamento e digestão (feita por meio de suas hifas) de animais muito pequenos ou microscópicos.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
&lt;span style=&quot;box-sizing: border-box; font-weight: 700;&quot;&gt;Reprodução&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Os fungos apresentam fases reprodutivas diferentes durante seus ciclos de vida: uma assexuada e outra sexuada.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
• Reprodução assexuada:&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
A reprodução de um fungo filamentoso se dá pela ruptura do micélio, gerando fragmentos que podem originar novos micélios. Esse tipo de reprodução assexuada é denominada fragmentação.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Nas leveduras, seres unicelulares, a reprodução acontece por divisão celular, recebendo o termo brotamento quando esta divisão origina duas ou mais células-filhas.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Nos fungos, em algumas regiões do micélio, existem hifas especiais, que possuem em sua extremidade uma estrutura de formato esférico, o esporângio. No interior do esporângio, ocorre a produção de esporos por mitose, processo conhecido como esporulação. Terminado este processo, sua parede se rompe e libera os esporos, que podem originar uma nova hifa que formará um micélio, dando continuidade a esse ciclo de vida.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
• Reprodução sexuada:&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
A reprodução sexuada segue um padrão constituído por três etapas.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
A primeira delas recebe o nome de plasmogamia, em que ocorre a fusão das hifas haploides (n). Esta etapa gera uma estrutura celular composta de dois núcleos haploides (n+n).&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Após um tempo, os núcleos gaméticos se fundem, etapa conhecida como cariogamia, originando um zigoto diploide (2n). Este zigoto entra em divisão meiótica, terceira etapa da reprodução, e produz células-filhas que darão origem a esporos haploides (n). O núcleo desses esporos sofre várias divisões meióticas, constituindo-se, assim, novas hifas.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
&lt;span style=&quot;box-sizing: border-box; font-weight: 700;&quot;&gt;Classificação&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
• Fungos sem corpo de frutificação:&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Inclui quitridiomicetos e zigomicetos, cujas células não possuem estruturas especiais no período reprodutivo.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Quitridiomicetos: são cerca de 800 espécies de fungos, que são consideradas menos especializadas que as outras. Vivem em água doce ou salgada e existem em diversas regiões do planeta. Eles podem ser parasitas ou saprófagos. A característica mais marcante desse grupo é a presença de células com flagelo em alguma fase da vida, o que ajuda na sua locomoção na água.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Zigomicetos: há cerca de mil espécies. São saprófagos que vivem no solo e se alimentam de matéria orgânica em decomposição.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
• Fungos com corpos de frutificação:&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
São aqueles que possuem uma estrutura formada por um arranjo de hifas de micélio reprodutivo (corpo de frutificação).&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Ascomicetos: As leveduras são unicelulares. A maioria dos ascomicetos possui talo filamentoso e suas hifas possuem septos transversais perfurados para que o citoplasma e o núcleo possam se mover de uma célula para outra. Estas células normalmente possuem apenas um núcleo. A parede celular é composta de quitina.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Basidiomicetos: Neste filo estão os cogumelos comestíveis e os venenosos, os orelhas-de-pau e as ferrugens, assim como parasitas e mutualísticos. Contém a estrutura do micélio bem desenvolvida.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
&lt;span style=&quot;box-sizing: border-box; font-weight: 700;&quot;&gt;Mutualismo&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
O mutualismo é uma relação ecológica harmônica onde há a associação de duas espécies diferentes para obtenção de benefícios, podendo depender ou não uma da outra para sobrevivência. Os casos apresentados são dois exemplos de mutualismo obrigatório de grande relevância para o estudo dos fungos:&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
• Mocorrizas:&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Há também as micorrizas, fungos que se associam a raízes de algumas plantas, sendo que os fungos contribuem com a absorção de nutrientes do solo, o que beneficia a planta, e a planta fornece aos fungos nutrientes orgânicos, numa relação de mutualismo.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Micorrizas são associações mutualísticas entre fungos e raízes formadas quando as hifas de um fungo invadem as raízes de uma planta. Diversos estudos apontam que esta relação foi muito importante para as plantas se fixarem em ambiente terrestre, pois os solos eram muito pobres em nutrientes, então os fungos ajudavam na absorção de nutrientes.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Nesta associação, os fungos auxiliam da absorção de nutrientes minerais (principalmente fósforo) do solo e da água e na proteção contra fungos patogênicos e pequenos vermes. Como troca, a planta fornece substâncias orgânicas fotossintetizadas essenciais para o crescimento dos fungos.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
As micorrizas são utilizadas em várias áreas de pesquisa, no desenvolvimento de mudas em viveiro e para aumentar o rendimento agrícola.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
• Liquens:&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Os liquens são formados pela associação mutualística entre fungos (geralmente ascomicetos) e algas (geralmente cianofíceas) ou cianobactérias. Nesta relação, as algas fornecem matéria orgânica produzida através da fotossíntese para o fungo. Em troca, ele retém umidade e nutrientes e dá proteção e um ambiente favorável para o desenvolvimento das algas. Quando a associação acontece com cianobactérias, um dos benefícios pode ser o aproveitamento do nitrogênio atmosférico como alimento.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Por serem resistentes a mudanças de temperatura, esses organismos são muito comuns. No entanto, são muito sensíveis à poluição, sendo considerados bioindicadores de poluição.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
O fungo se reproduz individualmente produzindo esporos assexuais ou sexuais. Já o indivíduo autótrofo, se reproduz apenas assexuadamente, por fragmentos que se soltam do talo (nome dado ao corpo do líquen). Outra forma de reprodução é do líquen inteiro, onde a reprodução é assexuada e ocorre por sorédios (células de algas e hifas de fungos) transportadas pelo vento.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
&lt;span style=&quot;box-sizing: border-box; font-weight: 700;&quot;&gt;Doenças&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
• Onicomicose&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
A onicomicose é uma infecção fúngica das unhas e pode ser considerada um problema muito difícil de tratar. A maioria das pessoas que possuem onicomicose não procuram tratamento, e talvez nem sequer tenham conhecimento da infecção.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Há três grupos de fungos que causam essa complicação, são eles: as leveduras (fungos como o Trichophyton rubrum), os dermatófitos (fungos como o Candida albicans) e os não dermatófitos (como o Microascus brevicaulis).&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
A onicomicose é considerada uma infecção patogênica, principalmente em pessoas que possuem o sistema imunológico fragilizado. Em muitos desses casos pode ser fatal, então não negligencie, procure tratamento o quanto antes.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
• Peniciliose&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
O Penicillium é um género de fungos, o comum bolor do pão, que cresce em matéria orgânica morta, como queijo, cereais ou fruta. Várias espécies produzem bactericidas (antibióticos) que permitem ao fungo lutar contra a competição feroz das bactérias saprófitas pelo alimento.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Algumas espécies de Penicillium causam infecções na pele e no trato respiratório do homem, nomeadamente em indivíduos imunodeprimidos, como os doentes com síndrome de imunodeficiência adquirida (SIDA ou AIDS).&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
A peniciliose é semelhante à criptococose, com febre e anemia. É a mais frequente causa de infecções oportunistas em doentes com SIDA/AIDS no Sudoeste. As infecções dos pulmões generalizam-se em casos graves podendo advir a morte.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
• Murcomicose&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
A murcomicose, antigamente conhecida como zigomicose, é uma doença causada pelos fungos que pertencem à ordem Mucorales. Esses fungos podem causar infecções pulmonares, gastrointestinais, cutâneas ou rinocerebral (invasão que ocorre no cérebro por meio dos seios nasais).&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Os fungos desse gênero são muito comuns, eles podem ser encontrados em mofo de pão, por exemplo, porém a maioria dos casos ocorrem devido a inalação de esporos lançados no ar. Os pulmões e seios nasais são os locais mais comuns em que a infecção tem início.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Os casos menos frequentes ocorrem pela ingestão de alimentos contaminados, mas a probabilidade que a infecção causada por fungos da ordem Mucorales ocorra, é algo que dependerá muito do hospedeiro, pois pessoas saudáveis não são suscetíveis a este tipo de infecção.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
• Candidíase&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
A candidíase possui esse nome pois é causada por diferentes espécies de leveduras da família Candida. Essa levedura é bastante comum nos seres humanos.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Muitas delas vivem pacificamente em nossos corpos, elas estão presentes em superfícies úmidas, como na boca, intestino e até mesmo no órgão reprodutor feminino, podendo causar infecção vaginal.&lt;/div&gt;
&lt;div style=&quot;box-sizing: border-box; margin-bottom: 10px;&quot;&gt;
Já as infecções que ocorrem na boca ou na garganta, desencadeiam quando a levedura invade a corrente sanguínea e se espalha por diversas áreas do corpo. A candidíase também pode ser fatal em casos de pessoas que possuem o sistema imunológico fraco.&lt;/div&gt;
&lt;/div&gt;

Olá pessoal, hoje viemos aqui relatar a vocês mais uma de nossas experiências sobre os vírus fitopatógenos, que são aqueles que atacam as plantas. Nós, alunos do Colégio Militar de Porto Alegre, realizamos uma visita ao Parque Farroupilha, guiados pelo professor Antonio Paim e observamos as plantas de lá.&amp;nbsp;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
Ao vermos as folhas mais detalhadamente, observamos a presença alterações nelas, como deformações, pigmentos coloridos, furos, algumas rasgadas e descascamento de caules. Essas alterações nas folhas das plantas se deve as vírus, transmitidos por meio de insetos, pólen de outras plantas, fungos, etc. Vale lembrar que para cada espécie de planta existe mais de cem vírus que a afeta.&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
As imagens abaixo foram capturadas por nós alunos e nos mostram como são as alteações citadas.&lt;/div&gt;

&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-size: 16.0pt;&quot;&gt;- Primeiras idéias sobre
classificação&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
No século IV a.C. , nasceu e
viver na Grécia o filósofo e naturalista Aristóteles. Ele realizou importantes
observações acerca dos seres vivos, descreveu aspectos de seu comportamento,
reprodução e habitat. &lt;/div&gt;
&lt;div align=&quot;center&quot; class=&quot;MsoNormal&quot; style=&quot;text-align: center; text-indent: 36.0pt;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;&amp;nbsp;&lt;img alt=&quot;Resultado de imagem para aristoteles&quot; src=&quot;http://www.efecade.com.br/wp-content/uploads/2013/01/ARISTOTELES-1.jpg&quot; /&gt;&lt;span style=&quot;text-indent: 36pt;&quot;&gt;&amp;nbsp;&lt;/span&gt;&lt;span style=&quot;font-size: 8pt; text-indent: 36pt;&quot;&gt;(Escultura feita
de Aristóteles)&lt;/span&gt;&lt;/div&gt;
&lt;div align=&quot;center&quot; class=&quot;MsoNormal&quot; style=&quot;text-align: center; text-indent: 36.0pt;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
Aristóteles criou uma
classificação, que se baseava por ordem de complexidade, e o interessante é que
o ser humano estava no ápice, seguido pelos outros animais, depois as plantas e
na base os minerais. Essa classificação persistiu até o século XIX.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
Santo Agostinho, filósofo e
teólogo que viveu no século IV d.C., propôs uma classificação baseada na
relação dos animais com o ser humano; assim ele separava em úteis, indiferentes
ou nocivos ao ser humano.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div align=&quot;center&quot; class=&quot;MsoNormal&quot; style=&quot;text-align: center; text-indent: 36.0pt;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;&amp;nbsp;&lt;img alt=&quot;Resultado de imagem para santo agostinho&quot; src=&quot;http://oracoespoderosas.info/wp-content/uploads/2016/06/santo-agostinho.jpg&quot; /&gt;&lt;span style=&quot;font-size: 8pt; text-indent: 36pt;&quot;&gt;(Retrato de Santo Agostinho)&lt;/span&gt;&lt;/div&gt;
&lt;div align=&quot;center&quot; class=&quot;MsoNormal&quot; style=&quot;text-align: center; text-indent: 36.0pt;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
Com o decorrer do tempo, as
classificações passaram a basear-se em descrições cada vez mais detalhadas e
cuidadosas, resultantes do estudo da morfologia (estrutura anatômica e
fisiologia). Durante o século XVI, épocas das Grandes Navegações, a cada
expedição que voltava, traziam inúmeros exemplares de plantas e animais até
então desconhecidos. Todos esses organismos passaram a ser descritos, nomeados
e classificados.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-size: 16.0pt;&quot;&gt;- Primórdios da taxonomia&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
Taxonomia é o ramo da biologia
que identifica, descreve, nomeia e classifica os seres vivos &lt;st1:personname productid=&quot;em categorias. As&quot; w:st=&quot;on&quot;&gt;em categorias. As&lt;/st1:personname&gt;
categorias taxonômicas são subdivididas em outros táxons, obedecendo a
critérios. &lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
* &lt;span style=&quot;font-size: 14.0pt;&quot;&gt;A classificação de Lineu&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
No século XVIII, o sueco Lineu,
afirmou que a natureza estava dividida em três reinos: vegetal, animal e
mineral. Ele dividiu cada reino em classes; cada classe, em ordens; cada ordem,
em gêneros; e cada gênero, em espécie. &lt;/div&gt;
&lt;div align=&quot;center&quot; class=&quot;MsoNormal&quot; style=&quot;text-align: center; text-indent: 36.0pt;&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;&amp;nbsp;&lt;img alt=&quot;Resultado de imagem para lineu&quot; src=&quot;http://www.algosobre.com.br/images/stories/assuntos/biografias/Carl_Lineu.jpg&quot; /&gt;&lt;span style=&quot;text-indent: 36pt;&quot;&gt;&amp;nbsp;&lt;/span&gt;&lt;span style=&quot;font-size: 8pt; text-indent: 36pt;&quot;&gt;(Retrato de
Lineu)&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
A contribuição mais importante de
Lineu foram as regras de nomenclatura científicas. Ele reduziu os nomes das
espécies a apenas duas palavras (binominal): a primeira para o gênero e a
segunda para a espécie. Regras:&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
- O gênero deve ter sempre a
inicial maiúscula.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
- A segunda palavra deve ser
escrita em letras minúsculas e é sempre precedida pelo gênero&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
- Os nomes devem ser escritos em
latim ou palavras latinizadas.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
- Em textos impressos as duas
palavras devem estar destacadas em itálico, e em textos escritos, elas devem
ser sublinhadas separadamente.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
- Quando o texto se refere ao
gênero como um todo, o nome pode ser seguido apenas da abreviação “sp.”.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
Exemplo totalmente correto: &lt;i&gt;Homo sapiens.&lt;/i&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
&lt;span style=&quot;font-size: 14.0pt;&quot;&gt;*
Categorias taxonômicas atuais&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
Os níveis taxonômicos atuais são
dispostos do mais abrangente pro mais específico: &lt;b&gt;reino, filo, classe, ordem, família, gênero e espécie.&lt;o:p&gt;&lt;/o:p&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div align=&quot;center&quot; class=&quot;MsoNormal&quot; style=&quot;text-align: center; text-indent: 36.0pt;&quot;&gt;

&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-size: 16.0pt;&quot;&gt;- Sistemática Filogenética&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
Antigamente, a classificação
fundamentava-se principalmente em aspectos morfológicos (semelhanças na forma
ou estrutura).&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
O problema é que nem sempre as
semelhanças morfológicas refletem relações reprodutivas entre as espécies. &lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
Um exemplo: a aparência externa
de um golfinho assemelha-se à de um tubarão. Entretanto, golfinhos são
evolutivamente mais próximos, por exemplo, das girafas, que também são
mamíferos.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
Em 1966, o alemão Willi Hennig
propôs que a classificação expressasse as relações de parentesco evolutivo
entre as espécies. O sistema que considera essa proposta recebeu o nome de &lt;b&gt;sistemática filogenética.&lt;/b&gt; &lt;/div&gt;
&lt;div align=&quot;center&quot; class=&quot;MsoNormal&quot; style=&quot;text-align: center; text-indent: 36.0pt;&quot;&gt;

Willi Rennig)&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
Essa sistemática a variedade de
organismos é gerada de duas formas:&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
- Cladogênese: conjunto de
processos que tem como resultado a origem de duas novas espécies.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
- Anagênese: conjunto de
processos  que gera mudanças graduais e
sucessivas em uma espécie. Podem resultar no surgimento de uma nova espécie.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
&lt;span style=&quot;font-size: 16.0pt;&quot;&gt;-
Evolução e especiação&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
No século XIX a concepção
predominante era o fixismo. Segundo os fixistas, as espécies eram imutáveis e
haviam sido criadas há muito tempo, exatamente da forma como são hoje.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
Porém Darwin sugeriu que os
organismos não eram imutáveis. Um exemplo relatado pelo naturalista é a
variação na forma do bico dos tentilhões, aves presentes nas ilhas Galápagos. &lt;/div&gt;
&lt;div align=&quot;center&quot; class=&quot;MsoNormal&quot; style=&quot;text-align: center; text-indent: 36.0pt;&quot;&gt;
&amp;nbsp;&amp;nbsp;&lt;img src=&quot;https://darwinismo.files.wordpress.com/2015/10/tentilhoes_darwin.jpg&quot; /&gt;&lt;span style=&quot;font-size: 8pt; text-indent: 36pt;&quot;&gt;(Variação na
forma do bico dos tentilhões)&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
Ele propôs a teoria de que as
condições ambientais selecionariam de forma distinta indivíduos com pequenas
diferenças entre si, favorecendo alguns com características vantajosas à
sobrevivência sob tais condições.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
Ele dominou &lt;b&gt;seleção natural&lt;/b&gt; o mecanismo que torna possível o processo de
evolução. &lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;b&gt;&lt;span style=&quot;font-size: 14.0pt;&quot;&gt;*Conceito de espécie &lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
É o conjunto de populações
naturais, isoladas reprodutivamente de outros organismos, que podem cruzar e
produzir descendentes férteis. &lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;b&gt;&lt;span style=&quot;font-size: 14.0pt;&quot;&gt;*Especiação &lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
É e formação de novas espécies a
partir de uma população já existente.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
Causas mais comuns:&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;b&gt;Isolamento geográfico:
&lt;/b&gt;ocorre quando surge uma barreira geográfica entre os organismos de uma
população, impedindo a reprodução entre os indivíduos dos grupos separados.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;b&gt;Redução de fluxo
gênico: &lt;/b&gt;ocorre quando não há uma barreira geográfica, mas por outros
motivos a reprodução entre alguns indivíduos de uma população é muito
improvável.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;b&gt;&lt;span style=&quot;font-size: 14.0pt;&quot;&gt;*Árvores filogenéticas&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
As relações de parentes
evolutivos são muitas vezes representadas através de diagramas, chamados de árvores&lt;b&gt;&lt;span style=&quot;font-size: 14.0pt;&quot;&gt; &lt;/span&gt;&lt;/b&gt;filogenéticas
ou cladogramas. &lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
Em uma arvore filogenética,
parte-se de uma raiz, que se ramifica. A extremidade de cada ramo representa um
táxon. Os pontos de ramificação representam espécies ancestrais ou eventos de
especiação.&lt;/div&gt;

Em 1990, o biólogo Carl Woese
propôs uma classificação de acordo com semelhanças e diferenças moleculares
entre ácidos nucléicos e certas proteínas do organismo. Segundo essa
classificação, os seres vivos são agrupados em três domínios:&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-indent: 36.0pt;&quot;&gt;
