The heart is the organ that helps supply blood and oxygen to all parts of the body. It is divided by a partition or septum into two halves‚ and the halves are in turn divided into four chambers.

This amazing muscle produces electrical impulses that cause the heart to contract‚ pumping blood throughout the body. The heart and the circulatory system together form the cardiovascular system.
