The heart is the hardest working muscle in the body. The heart, located near to the centre of the chest, is made up of four chambers that pump and circulate blood, oxygen and carbon dioxide around the body. It is continually working whether we are resting, doing activity or sleeping. For us to function at any level our body not only needs to be furnished with nutrients and oxygen but also requires a system that removes waste and carbon dioxide. The blood is responsible for this process, but it is the heart that makes it possible. The following pages discuss the anatomy of the heart.
