Question

Quizplus · Accepted Answer

The atrioventricular (AV) valves, including the tricuspid valve and the mitral (bicuspid) valve, prevent backflow of blood added into the atria during ventricular contraction. The aortic and pulmonary semilunar valves control the flow of blood out of the heart, not into it.
