   The heart is made up of four different blood-filled areas, and each of these areas is called a chamber. There are two chambers on each side of the heart. One chamber is on the top and one chamber is on the bottom. The two chambers on top are called the atria (say: AY-tree-uh). The heart has a left atrium and a right atrium.

The heart is relaxed and blood flows into both sides from the veins. The right and left atrium contract. Blood is forced into the right and left ventricles.

   How does the heart work?

   • The heart acts as a pump to push the blood throughout the body. The heart is separated into four chambers, or parts.

The valves control the movement of blood through the heart.
