Quizplus · Accepted Answer

The valves in the heart, including the atrioventricular (AV) valves and semilunar valves, function to prevent the backflow of blood to the chambers it has just left. The AV valves prevent blood from flowing back from the ventricles to the atria, while the semilunar valves prevent blood from flowing back from the aorta and pulmonary artery to the ventricles.
