The heart is an organ that pumps blood throughout the body. It comprises four chambers:

Atria (upper chambers)
Ventricles (lower chambers)

The wall of the heart is made up of three layers:

Epicardium- This is a protective layer made of connective tissues.
Myocardium- This layer forms the heart muscles.
Endocardium- This is the innermost layer and protects the valves and the heart.
