| Muscular organ the size of a closed fist, located behind the sternum (breast bone) and between the lungs. The pumping action of the heart circulates blood throughout the body. The heart consists of two upper chambers, the right atrium (pl. atria) and the left atrium, the two lower chambers the right ventricle and the left ventricle. Valves of the heart keep the blood flowing in one direction. The cardiac septum seperates the right and left sides of the heart. |
