Which vessel transports blood from the upper portion of the body to the heart?

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

Answer: (A)

Blood returning from the upper part of the body is carried by a large vein that empties into the right atrium. This vessel collects deoxygenated blood from regions above the diaphragm—such as the head, neck, and upper limbs—and returns it to the heart for re-oxygenation. In contrast, the aorta carries blood away from the heart to the body, the inferior vena cava drains blood from the lower body, and the pulmonary artery carries blood from the heart to the lungs. So, the vessel that transports blood from the upper portion of the body to the heart is the superior vena cava.
