perfusion process definition
Perfusion refers to the flow of blood through the veins and arteries of the body. Poor perfusion may cause organ failure. Perfusion is a common cause of amputation after an injury. In perfusion, blood moves from the heart, through a network of arteries and into the smallest blood vessels in the body.
In the process of perfusion, blood moves its way out from the heart, through a network of arteries, and into the smallest blood vessels in the body, the capillaries. As the blood flows through the capillaries, it brings vital nutrients to the tissues of the body, and helps to sweep away waste.
