Detailed explanation-1: -The inferior vena cava is ultimately responsible for the transport of almost all venous blood (deoxygenated) from the abdomen and lower extremities back to the right side of the heart for oxygenation.
Detailed explanation-2: -The separation between the subcardinal vein and the right posterior cardinal vein joins with the hepatic vein forming the inferior vena cava, which delivers deoxygenated blood from the lower limbs and abdominal viscera to the right atrium[8].
Detailed explanation-3: -Together, your superior vena cava and inferior vena cava collect deoxygenated blood from your whole body and bring it back to your heart for new oxygen. This is why the vena cava veins are the largest veins in your body.
Detailed explanation-4: -(i) Left atrium receives oxygenated blood from different parts of the body while right atrium receives deoxygenated blood from lungs.
