Rabbit is guarded by________ semilunar values.
a. 2 b. 4 c. 3 d. 1​

Answer 1

The right atrioventricular valve is also known as the tricuspid valve, since it has three cusps, or flaps, that open and closes. When this valve is open, blood flows freely from the right atrium into the right ventricle. However, when the right ventricle begins to contract, the valve closes, so that blood cannot return to the right atrium; this ensures forward flow into the pulmonary artery.

So, the correct answer is option D.
