Answer #1

The correct statement is option A. The atrioventricular (AV) valves prevent backflow of blood added into atria during ventricular contraction. These valves closes during ventricular contraction to prevent backflow of blood.

(B). Aortic and pulmonary semilunar valves control the flow of blood away from the heart.

(C). The mitral (bicuspid) valve separates the left atrium from the left ventricle.

(D). The tricuspid valve divides the right atrium from the right ventricle.
