Each half of the heart contains an upper and a lower communicating chamber-the atrium and ventricle,respectively.The RA receives desaturated blood from the inferior and superior venae cavae and from coronary circulation via the coronary sinus.The LA receives oxygenated blood from the lungs by way of the pulmonary veins.From both atria,blood then flows through the AV valves into the ventricles.The LV pumps oxygenated blood into the major vessels of the systemic circulatory system by way of the aorta and its main branches to the head,upper extremities,abdominal organs,and lower extremities.
