There are two atria (left and right atrium), and two ventricles (left and right ventricles).
The left side and right side are totally separated, but on each side the atrium and ventricle gets connected by a valve and has valves to either take in or pump out blood.
The term for the 4 sections of the heart muscle is the cardiac muscle.
