Which vessel carries deoxygenated blood from the head, arms, and chest to the right atrium?

• A. Superior Vena Cava
• B. Inferior Vena Cava
• C. Pulmonary Artery
• D. Aorta

Answer: (A)

The vessel that brings deoxygenated blood from the head, arms, and chest back to the heart and into the right atrium is the superior vena cava. It collects blood from the upper body and channels it directly into the right atrium, part of the systemic venous return. By contrast, the inferior vena cava handles the lower body’s return, the pulmonary artery carries blood from the right ventricle to the lungs, and the aorta distributes oxygenated blood from the left ventricle to the body.
