The heart is part of the Cardiovascular System and is found in the human body in the left centre (between the [[Lungs|lungs]). Its function is to pump oxygenated blood around the body and to collect deoxygenated blood. These two processes are seperated into the heart' left and right hand side respectively which are subdivided into chambers .
