A Labelled Diagram of The Human Heart

Understanding the Uniqueness of the Human Heart

2012-05-09T08:00:00.002-07:00

What is this astonishing organ called the human heart? This organ which is the vital part of our being, without it our body will not function, what especially makes this organ so important that when mentioned in poetry, it warms us, but by mere mention of it by our doctors, alas! we are alarmed. So let's see what makes this organ the HEART of our being. The heart in anatomy is a hollow muscular organ in the middle of the chest just to the left of the centre that pumps through the body.

It's comprised of four chambers, the right and atrium (auricle), the upper part and the right and left ventricle, the lower part. It's weight around 10oz and beat on average of 50 -70 times per minute, 100,000 per day and a roughly 40 million times per year. At average lifetime of about 76years, it will beat for at least 3 billion times. it pumps around 500 gallons of blood everyday.

The heart is the body system power house because every organ and tissues in the body needs a continuous supply of blood to function normally, especially the circulatory system, the brain and even the heart itself. If the heart does not pump blood for a few minutes, death will be the result.

The heart is made primarily of muscle tissues that rhythmically contracts to pump blood to all parts of the body. This start from when you are born to entire lifetime.

The upper part, i.e. the atria or auricle acts as a collecting reservoir while the lower part, the ventricle contract to pump the blood on. The right side of the heart receives blood through vein coming from all over the body and pump the oxygen-poor blood that it has received to the lungs so that it can pick up oxygen form the air we breath in, while the left side then collect the oxygen-rich blood from the lung and pumps it to all the tissues and organs in need of oxygen.

There are four valves that prevent blood from flowing back to the heart. They are the pulmonary, aortic, mitral and the triscupic valves. The heart muscle medically known as myocardium requires a very good supply of oxygen in order to be able to pump blood different organs and tissues of the body. And this blood supply is provided by the coronary arteries and their branches

The heart is surrounded by a tough, double-layered sac known as the pericardium> which has an inner layer called the epicardium. The outer layer of the epicardium helps to hold the heart in place and between these two layers is a tiny space filled with fluid them from rubbing against each other when the heart contracts.
The coronary arteries come off the aorta (the largest blood vessel in the body). The right coronary artery is usually smaller and supplies the down side of the heart. The left artery has two main branches called the Circumflex and the anterior descending. These coronary arteries are so special that blood can flow through them into the heart muscles between heart beat i.e. as it relaxes.

The Heartbeat: the right and left halve of the heart contracts in unison to produce a single heartbeat. The two phase of heartbeat are called the systole where the heart chambers contract to move blood and the diastole where the heart chambers are relaxing between a beat. Because of these two phases, the heart is able to pump much blood with each beat.

The Human Heart

2012-05-09T07:52:00.000-07:00

The heart is truly the most fascinating part of the body. From the moment it begins beating, right until the moment it stops, the human heart works without a break. In an average lifetime, the heart beats more than two and a half billion times, without ever pausing to take rest. And as it beats, it gives LIFE and keeps us going.

No other organ has caught the imagination of painters and poets alike. The heart is purest theater, throbbing in its cage palpably as any nightingale. Let danger threaten, and the thrilling heart skips a beat, and tight-rope walks rhythmically. And all the while, we feel it, hear it even - WE, its stage and its audience.

It was not the livers or brains or entrails of saints that were lifted from the body in autopsy. It was the heart they cradled into worshipful palms, then soaked in wine and herbs and set into silver reliquaries for the veneration of the faithful.

It follows quite naturally that the magnificent Love should choose such an organ for its bower. When Love blooms therein, the heart dances with joy - and tremor cordis is upon one!

The human heart has from time immemorial been surrounded by an aura of mystery and awe. Although some of this has been dispelled by the "cold reality" of modern science and technology, which has unravelled the mechanics of the heart, the air of fascination and wonder that the heart inspires in man has not diminished.

The Human Heart is Double Edged

2012-04-29T18:32:00.000-07:00

Anatomy of the Tony Walsh, in English, by Ties van Brussel / http://www.tiesworks.nl (Photo credit: Wikipedia)

The human heart cuts both ways. It's spontaneous... but also very obligated and loyal to tradition - both simultaneously. These are the traditions our habits have built into our life as we grew up, forming our particular perceptions, attitudes and beliefs. The impetuous heart's first impressions make it the most reliable of truth-verifiers - a quick read. And yet those very truth-impressions are bound partly to secret promises built, to a greater or lesser extent, upon censorship and concealment (explained below).

The heart's spontaneity gives it the impression that it's free of all obligations and encumbrances. Yet its quick responses to experience are possible because the heart's judgment obeys well-established attitudes, anchoring it to the bedrock of our beliefs about what things mean when we interact with life.

For most of us our common assumption is that our life has been built upon positive emotional experiences, which we try and reinforce and repeat every day. When in fact all human life is built upon a relatively even mixture of positive and negative occurrence - though some people's negatives are much bigger than others. Yet until very recently in human history we have not been able to manage negative incidents that conflict with our deeply yearned-for participation in happiness. We have fundamentally denied and projected the authorship of negative events upon other forces, entities and other people, making of our world a profoundly dangerous and violent place - which is only now being modified in a very significant way.

These psychic strategies of denial and projection are normally discussed as "mental illness", meaning only the wackiest do it, when their use is universal. No completely sane person, for instance, would ever wage war, except to put an ethnic-annihilating tyrant out of business, a very recent motivation for war. For centuries, well into the 20th century, we've spent well over 90% of our time killing for profit - rape pillage, spoils and the acquisition of conquered land.

So what do censorship and concealment have to do with the evolution of our habitual attitudes of experience-perception? We like to pretend in this modern age that children are capable of being emotionally independent of their parents, so, among other things, they can teach us their wisdom. Nothing could be farther than the truth. If we suffer, so will they suffer, and be unable to do anything about it - except perhaps with other very involved adults who offer them a viable and intimate alternative model. But even with this help, children can't mess with the basic model of life their families have provided, or failed to... for better or worse.

The reason is very simple. To begin with only children can love unconditionally, though we pretend otherwise. To love unconditionally is a pretty good imitation of slavery; meaning the sacrifice of personal needs to render our responses perfectly suited to another person. Children know that; they consider it normal to be enslaved to the limitations of their families, unless as adults they choose to sort out and change their life on their own terms. Contrary to popular opinion character-change, the only kind that really does much is very difficult to achieve because it's very fearful and disruptive to the very habits and attitudes in which we have believed all our life. To change significantly means to break basic taboos.

So what do children do instead of what we pretend is possible? They enslave themselves to what their families can see, admit and believe in, willing to sacrifice all of themselves if necessary in order to protect their basic connection to those who ensure their survival. They adapt themselves to believe only what their families believe. Nothing less would make them capable of comfort. If family attitudes and perceptions defy what they, in their innocence, perceive, they censor their contradictory perceptions, concealing them even from themselves behind attitudes and beliefs about their life that prevent any awareness of this dissonance from ever surfacing in their conscious mind. As the prayer says, sinning can occur not just in "deed", but also in "thought" and "word".

These attitudes about their life usually produce negative beliefs about themselves that may prevent them from ever contradicting anyone important in life. If children have been significantly hurt by their parents they will subsequently their whole life suffer great hurt on the unconscious premise they don't deserve to be protected from it. They may complain about it; but they will still suffer it. Shame and guilt are always funded by this kind of undeserved and concealed self-censure.

When the human heart is reacting mostly out of spontaneous perceptions with no serious encumbrances of self-censure, or accusation of others, it deserves our delighted support. But when it runs into negative implications - for either the feeling person or their companion - instead of support it needs to be carefully explored with whatever thoroughness frees the emotion from its bonds of loyalty to false premises of shame, guilt and their repetitive daily accusations.

About Web Directory :

Definition

A web directory or link directory is a directory on the World Wide Web. It specializes in linking to other
web sites and categorizing those links.

A web directory is not a search engine and does not display lists of web pages based on keywords; instead,
it lists web sites by category and subcategory. Most web directory entries are also not found by web crawlers
but by humans. The categorization is usually based on the whole web site rather than one page or a set of keywords,
and sites are often limited to inclusion in only a few categories. Web directories often allow site owners to
submit their site for inclusion, and have editors review submissions for fitness.

Scope of Listing

Most of the directories are general in scope and list websites across a wide range of categories, regions
and languages. But some niche directories focus on restricted regions, single languages, or specialist sectors. One type of niche directory with a large number of sites in existence is the shopping directory. Shopping directories specialize in the listing of retail e-commerce sites.

Examples of well known general web directories are Yahoo! Directory and the Open Directory Project (ODP).
ODP is significant due to its extensive categorization and large number of listings and its free availability
for use by other directories and search engines.

However, a debate over the quality of directories and databases still continues, as search engines use ODP's
content without real integration, and some experiment using clustering. There have been many attempts to make
directory development easier, such as using automated submission of related links by script, or any number of
available PHP portals and programs. Recently, social software techniques have spawned new efforts of
categorization, with Amazon.com adding tagging to their product pages.

Directories have various features in listing, often depend upon the price paid for inclusion:

1. Free submission – there is no charge for the review and listing of the site
2. Reciprocal link – a link back to the directory must be added somewhere on the submitted site in order to
   get listed in the directory
3. Paid submission – a one-time or recurring fee is charged for reviewing/listing the submitted link
4. No follow – there is a rel="nofollow" attribute associated with the link, meaning search engines will give
   no weight to the link.
5. Featured listing – the link is given a premium position in a category (or multiple categories) or other
   sections of the directory, such as the homepage. Sometimes called sponsored listing.
6. Bid for position – where sites are ordered based on bids
7. Affiliate links – where the directory earns commission for referred customers from the listed websites

How to Draw Like Leonardo Da Vinci - The Heart

2011-07-09T10:48:00.000-07:00

t is interesting to see how doctors and scientists the world over are referring to the studies done centuries ago by a non-science person, to unravel the mysteries of modern day. Leonardo Da Vinci's anatomical study of the human heart is a case in point. This work was a part of a series of almost 200 drawings Da Vinci made in his later years. His understanding of the function of the heart valves has provided a fresh perspective to the ongoing research endeavors. His detailed coverage of the mitral valve has offered new ways to address its dysfunction. Therefore, any attempt to recreate these heart drawings must cover the significant aspects of his explorations. The following guide will help you draw like Leonardo Da Vinci:

• Reference. Among all of his anatomical works, the heart drawings are one of the most easily accessible. A large collection is available on the internet. You may also look for books or journals.

• Technique and Style. Da Vinci dissected several corpses to aid his learning and representation of anatomy. He carefully examined each part and organ from different angles and portrayed the structure of progressively created sections. Therefore, some drawings of the heart show longitudinal sections, some represent the transverse sections, and the others, the complete organ. Leonardo da Vinci supplemented all his drawings with explanatory notes. His interest in comprehending the functioning of the organ, apart from its structural frame, rendered these works much more complex and descriptive.

• Subject Coverage. As mentioned earlier, Da Vinci covered the heart in more than one form, like the heart alone, the heart with veins & arteries, the connection of heart with other organs (lungs and trachea), sections revealing the internal structure, and so on. Leonardo Da Vinci was the first one to conclude that the human heart is primarily a muscle and has four chambers - the upper two auricles and the lower two ventricles. From this point of view, the longitudinal section diagram holds considerable value. Overall, the human heart has a strawberry like shape that tapers down. Da Vinci lacked the knowledge that blood circulates in the body. He believed that the liver creates blood, which reaches lungs for cooling and the tissues use it up. Nevertheless, he made a breakthrough discovery of the eddy currents in the Aorta that regulate the functioning of the heart valve.

• Details. Once you have sketched the external fundamental shape of the heart, placing the pulmonary veins and arteries is not a difficult task. In the case of transverse and longitudinal sections however, keener observation and exactitude is required. Such drawings by Da Vinci are quite complicated and somewhat hazy, representing all the components with a varying degree of shading or checkered spaces.

Be extra cautious with shading and labeling of your work such that the parts appear in their natural shapes and forms.

The Body's Energy Centers

2011-06-18T06:43:00.000-07:00

Eastern philosophy and medicine, originating in ancient India and China, have traditionally regarded body structures and the life processes occurring within as inseparable. Their terminology resides halfway between structure and function and identifies certain entities in the human body, representing the flow of life energy and, in some sense, conduits for that flow that do not correspond to anatomical structures recognized by Western science and medicine. The chakras are the energy centers in a person's biological field and are responsible for his or her physiological and psychological condition as well as certain groups of organs. All vital functions of the human body are determined by energy that spins in the chakras. These can be defined as "whirlpools referred," and in Indian, they are considered "energy bursts" or "wheels."

The process of energy transformation happens exactly in these centers. Vital energy, along with blood, circulates around the meridians in the chakras and fuels all organs and systems in the human body. When the circulation in these meridians stagnates, the human body becomes susceptible to various disorders. An excellent preventative method, designed explicitly to battle such stagnation is Chi Gun, an ancient Chinese method for self-healing which activates the energy centers. Chi Gun teaches people to release the energy themselves by massaging specific areas corresponding to the different chakras.

There are 49 chakras mentioned in the Vedic Canons, seven of which are basic; 21 are in the second circle, and 21 in the third circle. According to the Vedis, there are multiple energy channels leading to different locations from the chakras. Three of these channels are basic. The first one, called "shushumna," is hollow and is concentrated in the spine. The other two energy pathways, "ida" and "pingala", are located on either side of the spine. These two channels are the most active in most people, while "shushumna" remains stagnant.
The seven basic chakras spin at high speeds in the body of healthy individuals but slow down in times of sickness or with advancing age. When the body is in a harmonious balance, the chakras remain partially open.

Closed chakras are unable to receive energy, leading to various disorders.

The first basic chakra, "Muladhara," is located at the base of the spine in the tailbone area. Life energy, which is at the core of a strong and healthy immune system, is stored in this chakra. It is impossible for a person to become sick, old or even to die, before exhausting his or her reserves of this vital energy. The very will for life is controlled by Muladhara. It is also in charge of the bones and joints, the teeth, the nails, the urinogenital system and the large intestine. The first symptoms of a malfunctioning Muladhara are unreasonable fear, faintness, lack of security or faith in the future, leg and foot problems, and intestinal disorders.
The interrupted activity of the Muladhara chakra causes lack of energy, digestive problems, diseases of the bones and spine, and nervous tension among others.

The second chakra, "Svadhistana," is located at the level of the sacrum, three or four fingers below the belly button. This chakra regulates the pelvis, the kidneys and sexual functions. We also feel other peoples' emotions through this chakra. Symptoms of a malfunctioning "Svadhistana" are kidney problems, cystitis and arthritis.

The third chakra, "Manipura," is found in the solar plexus area. This chakra is the center for storing and distributing energy produced by digestion and breathing. It is responsible for vision, the gastrointestinal system, the liver, the gall bladder, the pancreas and nervous system. Symptoms of a stagnant "Manipura" are as follows: increased and constant worrying, as well as stomach, liver and nervous disorders.
The fourth chakra, "Anahata," also called the heart chakra, is located in the chest area. We generate and receive love through this chakra. It is in charge of the heart, the lungs, the bronchi, the hands and the arms. Symptoms of stagnation include depression and cardiovascular imbalances.

The fifth chakra, "Vishudha," is located at the throat level and is the center of analytical skills and logic. This chakra sustains the skin, organs of hearing, along with the trachea and lungs. Symptoms include a lack of emotional stability, discomfort in the cervical spine, soar throats, difficulties communicating, and esophagus and thyroid ailments.

The sixth chakra, "Adjna," is located between the eyebrows and is called the "third eye." Here is the throne for the human brain. "Adjna" circulates energy to the head and pituitary gland and is also responsible for determining our harmonious development. If a person's "third eye" ceases to function properly, one might notice a decrease in intellectual ability, headaches and migraines, earaches, olfactory illnesses, and psychological disorders.

The seventh chakra, "Sahasrara," is found at the very top of the head and represents the apex where an individual's energy vibrates with the highest frequency. It is considered a spiritual center and the entrance to the body for cosmic energy. A stagnant "Sahasrara" can result in a decrease in or lack of inner wisdom, as well as a lack of basic intuition.

With this basic knowledge of the first seven chakras, we can address the question: "How do we use this information to locate the causes of our troubles and problems, and with the help of Eastern Medicine, learn to control the functions of the chakras ourselves?".

From the perspective of Eastern Medicine, our health depends on the distribution of our energy-consciousness informational field. A shortage of energy inevitably causes ailments. According to Tibetan Medicine, the only difference between youth and old age, and between a sick and healthy individual, is the difference in the rotating speed of the whirlpool energy centers of the chakras. If these different speeds are balanced, old people will rejuvenate and sick people will heal. Therefore, the best way to preserve and keep our health, youth and vitality is to restore and maintain a balanced movement of the energy centers.

The easiest way to keep the chakras balanced is through a set of physical exercises. Yannis called these not simply exercises, but rituals. These rituals allow the human body to mold its energy centers to an ideal level of function. The seven rituals, one for each chakra, must be performed together every morning and when not possible, in the evening. Skipping rituals unbalances energy distribution, and so for the best results, no more than one day per week should be missed. The daily chakra rituals are necessary not only for revitalizing the body, but also for achieving success in every facet of life. "Once you learn how to transform your energy, you will also become happier," concluded Yannis.

For learning these rituals (which have transformed many peoples' lives throughout the world), seeing them in action is much more effective than trying to follow written descriptions or diagrams. A DVD, available from Helix 7, Inc. (www.FeelingOfHappiness.com), includes actual demonstrations of these rituals.
Another method of keeping the chakras balanced and in their optimal half-open state is meditation. Meditative methods are universal to the human experience; they have accumulated over the ages through many different cultures and have proven their value in attaining peace, clarity, equanimity and in transcending despair. People who meditate on a regular basis are usually calmer, more secure, more joyful and more productive human beings. They are more effective in their everyday lives because they use their mental and physical potential, abilities and skills to their fullest extent. All too often, we humans fail to realize the great latent powers which are, as yet, unawakened in our bodies. We must learn how to revive and utilize them.

This can only be achieved through meditation. Eastern men of wisdom, who believed meditation to be a vital necessity, stumbled on this discovery more than 1000 years ago. They learned to influence their inner organs and control their metabolism with the power of their minds. Meditation is to the mind what exercise is to the body; mental strength can be built up just like physical strength. Just as in athletics, it is important for an individual to train his or her body, it is important for an individual to train his or her mind through meditation.

The best time for meditation is early morning, preferably at dawn. Do not meditate when you are sad, aggravated, desperate or sick, because these intense emotional and physiological distractions make an enlightened state of mind impossible. For an effective meditation session, it is preferable to arrange for the undistracted silence of a quiet, clean room with flowers, or the soothing sounds of Mother Nature - near a lake, river, waterfall, woods or fields.

Many different mental practices, having their origin in historical traditions, fall under the general heading of "meditation." These paths of mental development can involve emotional and intellectual facets and may also be coordinated with specific movements. Meditation can be structured or unstructured, Dr. Wayne W. Dyer writes in his book Real Magic, "The process of meditation is nothing more than quietly going within and discovering that higher component of yourself ... Learning to meditate is learning how to live rather than talking about it..."

The Structure of the Heart

Knowledge of the structure and function of the heart and other aspects of the vascular system, is an essential part of training in many therapies, such as Massage (in its many forms, "Indian Head Massage", "Swedish Massage", "Accupressure Massage" etc.), Aromatherapy, Accupuncture, Shiatsu, and others. This page is intended to include the detail required for most Basic / First Level Courses in these therapies, and some ITEC Diplomas.

The first diagram (immediately below) is a cut-away section through the heart, showing its physical appearance and labelling its major components and blood vessels. The simpler diagrams below it are line drawings including essential information in a form that is easier to reproduce in exams.
