The human body has two major sets of blood vessels that distribute blood from the heart to the body. One set pumps blood from the right heart to the lungs and the other from the left heart to the rest of the body. • The portion of the circulation that distributes oxygen-rich blood from the left side of the heart, throughout the body, is referred to as the systemic circulation. • The blood then returns from the body to the right side of the heart and passes through the lungs to replenish oxygen. • It then returns to the left side of the heart for another round through the systemic circulation. • The portion of the circulation that distributes the blood from the right side of the heart to the lungs is referred to as the pulmonary (lung) circulation. • The pulmonary arteries are the major blood vessels that carry blood from the right side of the heart to the lungs. The left ventricle of the heart pumps oxygenated blood (blood that has been reloaded with oxygen in the lungs) from the lungs
