Upper chamber of the heartPrevents blood movement from R. ventricle to R. atriumMembranes around heartGroove separating left and right ventriclesPrevents blood movement from L. ventricle to L. atriumInner lining of heart chamberLayer largely composed of cardiac muscle tissueSpace containing serous fluid to reduce friction during heartbeatsDrains blood from myocardial capillariesSupplies blood to heart muscleDistributes blood to body organs except lungsGroove separating atrial and ventricular portions of the heartThe visceral portion of the pericardium on the surface of the heartHelps open and close the valve during contractions

Vein Artery

Blood flowMajor veins and arteries

• The first part of a heart sound, ____occurs during the ventricular_______, when the A-V valves are closing.

• The second part of a heart sound, ____occurs during ventricular ______, when the pulmonary and aortic valves are closing.

• The external structures of the heart include the ventricles, atria, arteries and veins. Arteries carry blood away from the heart while veins carry blood into the heart. The vessels colored blue indicate the transport of blood with relatively low content of oxygen and high content of carbon dioxide. The vessels colored red indicate the transport of blood with relatively high content of oxygen and low content of carbon dioxide.
