D

Verified step by step guidance1
Step 1: Understand the anatomy of the heart and the flow of blood through its chambers. The superior vena cava is a large vein that carries deoxygenated blood from the upper body to the heart.
Step 2: Recall that the superior vena cava empties blood into the right atrium, which is the first chamber of the heart that receives deoxygenated blood.
Step 3: Eliminate the incorrect options by considering the sequence of blood flow. The left atrium and left ventricle are part of the oxygenated blood pathway, so they are not correct in this context.
Step 4: The right ventricle is the chamber that pumps blood to the lungs for oxygenation, but blood flows to the right atrium first before reaching the right ventricle.
Step 5: Conclude that the correct answer is the right atrium, as it is the chamber that directly receives blood from the superior vena cava.
