Question

Which of the following is least true of the aortic valve?
A) It is also called the left semilunar valve.
B) It "sees" oxygenated blood.
C) Blood flows from the ventricle through this valve into the pulmonary artery.
D) An incompetent aortic valve allows blood to leak from the aorta back into the left ventricle.

Accepted Answer

Blood does not flow from the ventricle through the aortic valve into the pulmonary artery. Instead, the aortic valve allows blood to flow from the left ventricle into the aorta, which then distributes oxygenated blood throughout the body.
