Time of systemic circulation

This is a time of the complete cycle of blood flow through the systemic circle vessels, related to five factors of the regulation of blood circulation in inner organs. These factors are indissolubly related to the regulation of water-electrolyte metabolism.

Systemic circulation is the part of the cardiovascular system, which carries oxygenated blood away from the heart to the body, and returns deoxygenated blood back to the heart.

Systemic circulation refers to the part of the circulatory system in which the blood leaves the heart, services the body's cells, and then re-enters the heart. Blood leaves through the left ventricle to the aorta, the body's largest artery. The aorta leads to smaller arteries, arterioles, and finally capillaries. Waste and carbon dioxide diffuse out of the cell into the blood, and oxygen in the blood diffuses into the cell. Blood then moves to venous capillaries, and then the venae cava: the lower inferior vena cava and the upper superior vena cava, through which the blood re-enters the heart at the right atrium.
