Detailed explanation-1: -What does the vena cava do? Your superior vena cava and inferior vena cava have the important function of carrying oxygen-poor blood to your heart’s right atrium, where it moves into your right ventricle and then to your lungs (through your pulmonary artery) to trade in carbon dioxide for oxygen.

Detailed explanation-2: -The vena cavae are the terminal parts of the extensive venous networks throughout the periphery returning deoxygenated blood to the heart. The inferior vena cava carries deoxygenated blood from the tissues below the diaphragm.

Detailed explanation-3: -Generally an artery carries oxygenated or pure blood in the body and veins carry deoxygenated or impure blood. But pulmonary artery is the only artery which carries impure or deoxygenated blood and pulmonary vein carries impure blood.
