Which of the Following Vessels Empties into the Right Atrium

Question

Which of the following vessels empties into the right atrium?
A) pulmonary trunk
B) pulmonary veins
C) superior vena cava
D) ascending aorta

Accepted Answer

The superior vena cava is a large vein that brings deoxygenated blood from the upper body to the heart, specifically to the right atrium. The pulmonary trunk carries deoxygenated blood away from the right ventricle towards the lungs, while the pulmonary veins carry oxygenated blood from the lungs back to the heart, but they empty into the left atrium. The ascending aorta carries oxygenated blood away from the left ventricle and is not connected to the right atrium.
