inferior vena cava
Body's lower drain
The inferior vena cava is the large vein that carries deoxygenated blood from the lower body back to the heart.
It collects blood from the legs, abdomen, and pelvis, delivering it to the right atrium.
The superior vena cava performs the same function for the upper body.
