Which of the Following Does Not Happen During Ventricular Diastole

Question

Which of the following does not happen during ventricular diastole?
A) Blood is being pumped into the great vessels.
B) The semilunar valves are closed.
C) Blood is filling the ventricles.
D) Blood is flowing from the atria into the ventricles.

Accepted Answer

During ventricular diastole, the ventricles are relaxed and filling with blood. The semilunar valves are closed to prevent blood from flowing back into the ventricles from the great vessels. Blood is flowing from the atria into the ventricles through the open atrioventricular valves. However, blood is not being pumped out of the ventricles during this time, so choice A is the correct answer.
