- The Heart is a hollow muscle that pumps blood to the whole body.
- It is located in the chest and between the lungs.
- It has a double-walled sac to protect it.
- It's function is to pump blood throughout the blood vessels to keep the body oxygenated, so that we can stay alive.

Muscle cells relate to the heart because when the heart contracts, it pumps blood and the muscle cells make the muscle contract.
