The heart pumps blood throughout the body supplying the tissues and organs with nutrients and oxygen and carrying away the waste products the body generates.

Blood is kept in motion in the body through the tireless work of a very efficient organ, the heart. It has four distinct chambers; a right and a left auricle (atrium) and a right and a left ventricle. The heart is really double pump and each part has its own particular job to do. The right half of the heart is concerned with the work of sending blood low in O2 and high on CO2 (deoxygenated) over the lung for oxygenation. Two large veins, one from the head regions and the other from the rest of the body (venae cavae), carry blood to the right auricle, while in turn, passes it on to the right ventricle through the tricuspid valve.

The right ventricle pumps the blood through the pulmonary valve into the pulmonary artery over to the lungs for oxygenation, and then through pulmonary veins into the left auricle. The particular task of the left half of the heart is to pump oxygenated blood to all parts of the body. Left auricular contraction then forces the blood through the bicuspid (mitral) valve into the left ventricle, from where it is pumped through the aortic valve into the aorta and through the aorta to the entire system. The bicuspid, the tricuspid, the pulmonary and the aortic valves block the passage of the blood back to the left auricle, the right auricle, the right ventricle and the left ventricle respectively. If, however, any valve is defective, some leakage or backflow of blood results.
