Which vessels flow into the Right Atrium from the body via the inferior or superior vena cava?

Explanation:
The question is about what type of vessel returns blood from the body to the heart through the vena cavae. Blood flowing via the superior and inferior vena cava into the right atrium is carried by veins, the vessels that return deoxygenated blood to the heart under low pressure. Arteries carry blood away from the heart, capillaries are the small exchange vessels between arterioles and venules, and venules are small veins that feed into larger veins. So the vessels entering the right atrium via the vena cavae are veins.
