Human heart. Artwork showing an external view of a healthy human heart,with abstract colours superimposed. The heart's main blood vessels are from left to right: superior vena cava (blue),aorta (red),pulmonary artery (blue),and the pulmonary veins (2 narrower vessels,red). The heart pumps blood around the body. It consists of four chambers: those on the left side (at right on image) receive oxygenated blood from the lungs and pump it to the body via the aorta. Blood drained from the body is pumped through the right side of the heart to the lungs,through pulmonary arteries. Special conduction mechanisms in the heart muscle maintain its pump-rhythm | |
