Which vessel returns blood from the upper body to the heart?

The blood from the upper body returns to the heart through the superior vena cava. This large vein collects deoxygenated blood from the head, neck, and upper limbs (via the brachiocephalic veins) and drains it into the right atrium, completing the systemic venous return from the upper body. For context: the inferior vena cava handles the lower body, the pulmonary artery carries blood away from the heart to the lungs, and arterioles are small arteries that carry blood away from the heart into tissues. The key idea is that venous return from the upper body uses the superior vena cava to reach the heart.
