The Normal Heart

Enlarge image

The heart is divided into 2 halves: left and right. Each half of the heart is divided into separate chambers — the upper ones, known as the atria, receive blood from the body whereas the lower ones, the ventricles, pump it out again. In between these chambers are the heart valves, which open and shut in sequence to make sure blood flows in the right direction. The valves are normally smooth and form a perfect seal when closed.
