Human circulatory system consists of essentially three main components namely; Heart  Blood Blood vessels Human heart Heart is a muscular pumping organ that provides blood to the body. External structure Heart is a conical shaped muscular organ. It is covered with a membrane called pericardium. In between the pericardium and heart wall is the pericardial fluid that also provides protection to subside the pressure directly on the heart wall. Location The heart is located between the lungs in the middle of the chest, behind and slightly to the left of breastbone which is called sternum. Internal structure Internally, heart consists of four chambers. Upper two chambers are called atria (right and left) while the lower chambers are called ventricles (right and left). Ventricles have thicker walls as compared to atria. The walls of left ventricle are thickest as it has to pump the blood to the whole body under greater pressure. Important ves
