Four Chambers of the Heart
The heart is made up of four different blood-filled areas, and each of these areas is called a chamber.

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 two chambers on the bottom are called the ventricles (say: VEN-trih-kulz). The heart has a left ventricle and a right ventricle.
