perfusion

per·fu·sion

/pər'fyo̅o̅′zhən/

Noun

Perfusion is how the body supplies the tissues with nutrients and oxygen and removes toxins and wastes. Venous blood containing various products returns from the cells and passes through various organs such as the kidney and lungs. Waste products as well as excess amounts of water and carbon dioxide are removed from the blood stream. The blood eventually returns to the heart where it is sent to the lungs to pick up a new load of oxygen for transport back to the cells. This continuous loop of pickup and drop off is known as perfusion. Adequate tissue perfusion occurs as a result of an adequately pumping heart, a vascular system that is intact, and enough blood volume within the blood vessels.
