How the heart works
... The superior vena cava and inferior vena cava carry deoxygenated (dark red) blood, which has circulated around the body, into the right side of the heart. The heart muscle then pumps the blood through the pulmonary artery to the lungs where it picks up a fresh supply of oxygen. At the same tim ...
