PREVENTION AND DIAGNOSIS OF CIRCULATORY DISEASES IN OLD AGE

The heart is a biological pump that moves blood through a closed system of vessels, pumping about 6 litres of blood every minute. Age-related changes in the circulatory system in old age severely limit its adaptive capacity and create conditions for developing diseases. In old and old people, the number of active capillaries per unit area is significantly reduced. Tissues and organs cease to receive the nutrients and oxygen they need, leading to starvation and disease. Cardiovascular disease is the most common cause of death in humans.
