Which of These Vessels Receive Blood During Ventricular Systole

Question

Which of these vessels receive blood during ventricular systole?
A) pulmonary arteries only
B) pulmonary veins only
C) both the aorta and pulmonary trunk
D) aorta only

Accepted Answer

During ventricular systole, both the aorta and pulmonary trunk receive blood from the ventricles. The aorta carries oxygenated blood from the left ventricle to the systemic circulation while the pulmonary trunk carries deoxygenated blood from the right ventricle to the lungs for oxygenation. The pulmonary veins carry oxygenated blood back to the left atrium, but they do not receive blood during ventricular systole.
