The heart is often used as a symbol of love that full of romantic. Actually, this symbol could mean as the organ that gives zest for life or a better life. If organ function is disturbed for any disease, then the patient will show the live load un-harmonious, such as severe pain or tightness in the chest which is generally perceived in people with heart disease.
If more serious damage to his heart, let alone to give a smile, to breathe oxygen need help. Even more fatal, if the heart stops working, the whole activity of life in the body must be stopped and death is unavoidable.
After we learn how the heart works, have we tried to understand the character of our heart? Have we tried to prevent us from damage to our heart? The heart is an organ of the body's that is working hard, day or night, the heart works 24 hours per day, then if the affection of our heart, we must take care as good as possible, because our heart is the most expensive organ, more expensive than all the treasures that we are looking for as long as life.
Heart weight is only 0.5% of our body weight, but it requires about 5% of the blood that flows in the body. This means that the heart requires nourishment as much as 10 times more than other organs. Cardiac absorbs nearly 80% of blood oxygen flows through, compared to 30% by other organs. Hearth weight is about 250 to 430 grams, it is about one fist of our hand.

Heart Form And Function
The heart is a hollow muscular organ of a conical form, placed between the lungs, and enclosed is the cavity of the pericardium.
The heart is placed obliquely in the chest; the bread attached end or base, is directed upward, backward, and to the right, and corresponds with the dorsal vertebrae, from the fifth so the eighth inclusive; the apex is directed downward, forward, and to the left, and corresponds to the space between the cartilages of the fifth and sixth ribs, three quarters of an inch to the inner side, and an inch and a half below the left nipple, or about three and a half inches from the middle line of the sternum. The heart is placed behind the lower two third of the heart lies to the heart is round and convex, directed upward and forward, and form chiefly by the right auricle and ventricle, together with a small part of the left ventricle. In posterior surface, which looks downward rather than backward, is flattened and rest upon the Diaphragm, and is formed chiefly by the left ventricle. The right or lower border is long, thin and sharp: the left or upper border short, but thick and round.
The Size of Heart
The heart, in the adult, measure five inches in length, three inches and a half in breadth in the broadest part, two inches and a half in thickness. The prevalent weight, in the male, varies from ten to twelve ounces; in the female from eight to ten; its proportions to the body being as 1 to 169 in males; 1 to 149 in females. The heart continue increasing in weight, and also in length, breadth and thickness, up to an advance period of life; this increase is more marked is men than in women.

Heart Attack First Aid
We will nervous if facing with heart attack to people. Heart attack is different with other diseases because heart attack is critical condition. If you decide or treat with wrong way it can be fatal and often can cause died. First aid to help people who have heart attack race against time, because heart attack is stopped supply of blood circulation to all the body organ.
When a heart attack strikes, the longer delay of seeking medical treatment, more heart muscle will be damaged. To make normal blood supply to all organ by heart is unblocked an artery with quickly to limit damage. This treatment must be done in a hospital and include injecting clotbusting drugs to dissolve of clot and angioplasty, where the blood vessel is opened by balloon often with placement of a stent.
We just can call to emergency number and give first aid if the patient can't breath, by make artificial respiratory. If the patient still breath we must as quickly as possible to bring the patient to the heat attack hospital. Hospital have estimated treatment plans to minimize the time to diagnose and treat people with heart attack. The National guidelines suggest that an electrocardiogram (EKG) be done within 10 minutes of the patient's arrival in the ER. Manything will be done at the same time while the EKG being completed, doctor will take the patient history and complete a physical exam while the nurses start an intravenous line, place heart monitor lines on the chest and administer oxygen.
Until now still very rare hospital can handle patient with heart attack with satisfactory. Only big hospital with enough experience and with complete equipment to treat every heart attack problem. A late help to heart attack patient will make fatal condition even dead.

Coronary Circulation
The blood supply to the heart muscle is furnished mainly by the coronary arteries, which originate from the aorta immediately after the aortic valve. These vessels pass through the fatty tissue beneath the pericardium and then branch out into the heart muscle. Deoxygenated blood is transported from the heart muscle to the right atrium by the coronary veins. The heart's energy supply is almost completely dependent on the coronary vessels. Only the tissues lying directly beneath the endocardium receive a sufficient amount of oxygen from the blood within the cavities of the heart.
The coronary arteries do not have any effective collateral circulation. That is, each part of the heart depends on its own coronary branch for its blood supply. If a branch becomes particularly or completely blocked through various heart diseases, the result can be a heart attack or lesser muscle damage. Spasms in the wall muscles of the coronary arteries can also result in obstruction that impede the flow of blood.
Heart Hormone
Like a member of other internal organs, the heart produces a hormone with regulatory effects on other body systems. The heart hormone is called atrial natriuretic factor. The name refer to its origin in the atria and its contributory role in maintaining proper the excessive loss of sodium and other cations in urine. Atrial natriuretic factor also has a strong hypotensive, or lowering, effect on blood pressure and of aldosterone by the adrenal cortex. These and other hormonal and neutral mechanisms all interact with one another in the control of salt and water levels in the body.
