The heart is a muscular organ that pumps blood to all the tissues in your body through a network of blood vessels. The right side of the heart pumps blood through the lungs where it picks up oxygen.

Your heart has four chambers and four valves that regulate blood flow: Left and right atria. Left and right ventricles.
