The heart is an organ that is mostly made up of muscle. It pumps the blood throughout the body by contracting.

The heart gets its instructions (the ones that tell it to pump) from the autonomous nervous system. This is unlike other muscles, such as those in our fingers, that only move when we tell them to. The heart contracts automatically, without us having to use our brain to tell it to contract.

The human heart is divided into four chambers. The chambers on the right pump blood to the lungs for oxygen while those on the left pump the oxygenated blood to the rest of the body.
