How the Heart Works
A normal heart is divided into four hollow chambers, two on the right and two on the left. In performing its basic job - pumping blood throughout the body - the heart uses its left and right sides for different tasks. The right side moves blood into vessels called pulmonary arteries, leading to the lungs. In the lungs, oxygen enriches the blood, which circulates to the heart's left side in blood vessels called pulmonary veins. The left side of the heart pumps blood into a large vessel called the aorta. Branching off from the aorta are numerous other vessels that circulate blood to the rest of the body.
