Question

Quizplus · Accepted Answer

The statement that correctly describes the function of the heart valves is B, as the atrioventricular (AV) valves prevent backflow of blood into the atria during ventricular contraction. The mitral (bicuspid) valve separates the left atrium from the left ventricle, while the aortic and pulmonary semilunar valves control the flow of blood out of the heart. The tricuspid valve separates the right atrium from the right ventricle.
