Structure
The heart is a large muscle in the centre of the chest. Using a stethoscope, it is possible to listen to it, and to diagnose problems within it.
Function
The heart is a big old pump, that transports blood around the body, allowing it to be oxygenated in the lungs, and thus supply oxygen to the body.
The contraction of the heart is synchronised using a complex conduction system.
