Which vessel carries blood toward the heart from the body?

Explanation:
Blood returning from the body to the heart travels in veins. Veins are designed to carry blood back to the heart, often with valves to prevent backflow and operate under low pressure. In the systemic circuit, deoxygenated blood from the body returns via the superior and inferior vena cavae into the right atrium, then moves to the right ventricle and onward to the lungs for oxygenation. Arteries carry blood away from the heart, and capillaries are the exchange vessels between arteries and veins, so they’re not the vessels that bring blood back to the heart from the body.
