Answer:
Body
Explanation:
The inferior vena cava carries oxygen-poor blood from the lower part of the body to the right atrium. The right atrium receives oxygen-poor blood from the body through the superior vena cava and the inferior vena cava and pumps the blood to the right ventricle.
The largest vein in the human body is the inferior vena cava, which carries deoxygenated blood from the lower half of the body back up to the heart.
