because our health depends entirely on the system krovobrascheniya. If we consider our body, it is to the vessels and capillaries can find the vulnerabilities that require an approach to their treatment or healing. 2 before a specific pressure. The walls of the arteries vary a great flexibility and superior strength. Large arteries have a good chance of human influence in the stand 20 atmospheres.
Perhaps the effect is needed to overcome anti-wall formed blood vessels and eventually forcing the heart and circulatory tonic tension personally wall. In the episode reduction (systole) of the heart arteries, the greatest influence in – 100-130 mm Hg. Art. it moves the title of systolic or maximum pressure. How soon after a heart placed in a state of calmness muscular relaxation (diastole) and the blood from his artery did not come, the impact of the vessels is reduced by 70-80 mm Hg. Art. Certainly diastolic blood or a small effect.
Left ventricular blood is ejected into the solid artery of the body – the aorta, a fairly wide tube, having a height (size) of 2-3 cm near the aorta branches into a number of large vessels are in the order of its own – for most small branches that are followed in different parts of the body. Continue to be distributed, dispersed, arterial vessels are the most stayut sensitive. In the end, the arteries become the most delicate blood vessels – capillaries ("capillary" vessels). They are so small, if they are allowed only to behold the microscope. Capillaries – an important fraction of the vascular system! specifically microvessels and blood flow in these vessels – microcirculation. Extraordinariness study of microcirculation in healthy people and its configuration in a number of diseases – an important research gaps. Clearly, if processes occurring in microvessels – mikrotsirkultsiya, personality, movement of blood cells snutri capillaries, individual passing through the walls of several drugs capillaries (transcapillary transport) are as would be at the junction of circulation and exchange of drugs in the cells of organs.
