An introduction to the human heart, its location within the human body and its function as a pump. The heart sits within the chest cavity between the lungs and is about the size of a fist. Essentially it is a muscle which functions as a really powerful pump. The heart takes in blood low in oxygen from the body. It pumps it through the right side of the heart and on to the lungs. In the lungs the blood passes through very small blood vessels and absorbs oxygen. The freshly oxygenated blood is pumped back through the heart and on to the rest of the body where the oxygen provides fuel for muscles and organs.
