Understanding the Uniqueness of the Human Heart

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

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

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.
