Which of the Following is a Result of Ventricular Contraction

Question

Which of the following is a result of ventricular contraction?
A) The AV valves open.
B) The semilunar valves close.
C) Blood is pumped into the pulmonary artery and the aorta.
D) Blood flows back into the atria.

Accepted Answer

Ventricular contraction, also known as systole, results in the closing of the semilunar valves and the opening of the AV valves. This allows blood to be pumped out of the ventricles and into the pulmonary artery and aorta, leading to circulation throughout the body. Blood flowing back into the atria would be a result of valve failure or regurgitation, not ventricular contraction.
