Heart

The heart is part of the Cardiovascular System and is found in the human body in the left centre (between the 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^[1] which are subdivided into chambers ^[2]. The Upper chambers are known as the Atria, and the lower chambers are called the ventricles.^[3]
