Which chamber receives deoxygenated blood from the body?

Explanation:
When blood returns from the body, it does so in a deoxygenated state and enters the heart on the right side. It flows into the right atrium via the superior vena cava from the upper body, the inferior vena cava from the lower body, and the coronary sinus from the heart muscle. The right atrium acts as the receiving chamber for this systemic venous return before blood moves to the right ventricle and then to the lungs for oxygenation. By contrast, the left atrium receives oxygenated blood from the lungs, and the left ventricle pumps oxygenated blood to the body. So the chamber that receives deoxygenated blood from the body is the right atrium.
