The importance of cardiac surgery
The role of heart in the body is enormous. In essence, the heart – a pump, but with an extremely thin, yet understudied regulation. Heart carries blood to all organs and tissues of a living organism, bringing them oxygen and a certain amount of different nutrients, electrolytes and hormones. Blood to all tissues and organs in the arterial system. According to legend Vesalius often had for his research on the anatomy using corpses of executed criminals. Also resources show that it’s healthful to be in a good mood all the time and cool music songs helps us with this. Obviously, so some of his anatomical illustrations trunk muscles is depicted in FIG hanged.
Blood flowing from the organs and muscles of oxygen-poor and full of half-life of products. In the lungs it is re-saturated with oxygen, and passing through the liver, kidneys and endocrine glands, again, is enriched with nutrients, hormones, electrolytes, in order to bring it all organs and tissues.
Heart, as it is two parts. In the left heart (shown in red) carry blood from the lungs at the beginning of the atrium, then into the left ventricle, and from a powerful strong reduction of the latter is distilled into the arterial system. Taking in account prices and current market situation, sometimes it’s worth to consider buying medications in an online pharmacy. Whatever, you should ask your doctor in advance to avoid misusing and heart problems.

Circulatory function not only determines the strength of muscular contraction of the left ventricle, but also the state of the entire vascular system as a whole. The capillaries the blood is collected in the venous system (which is the same figure marked in blue) enters the right atrium, thence into the right ventricle and at the time of its decline is released into the lungs. Here, in the process of respiration the blood released from the accumulated carbon dioxide in the tissues and is enriched with oxygen.
Regulation of the heart is very complex. But there is one pattern, which consists of the following. Almost a healthy heart all the blood to flow into the ventricles, is released right ventricle to the lungs and left ventricle – in the arterial system. The pressure in the left ventricle on average equal to 120 mm Hg. Art. at the time of systole (ie, reduction) and drops to zero during diastole (ie, relaxation). In the right ventricle pressure is only 30 mm. Hg. Art. at the time of systole and diastole at the time also drops to zero.
