Question

Which of the following valves will shut during diastole of the left ventricle?

• A. Bicuspid valve
• B. Tricuspid valve
• C. Pulmonary semilunar valve
• D. Aortic semilunar valve

Answer 1

The correct option is D

Aortic semilunar valve

During diastole of left ventricle, there is a suction created, which will cause blood from the aorta to be pulled back into the left ventricle. The aortic semilunar valve has to close, therefore, to prevent this from happening.
