Physiology of the Cardiovascular System

Cells in the body are in need of continuous nourishment, oxygenation and excretion of waste, otherwise they die. The only way these exchanges are made is via the tissue fluid (blood) that passes through it. This is where the cardiovascular system comes into the picture. The cardiovascular system is composed of blood, the blood vessels...
