The inferior vena cava takes blood from which of the following to the heart?
  1. Hepatic vein
  2. Hepatic portal vein
  3. Renal vein
  4. Both A and C
Explanation
Answer: - D - The inferior vena cava takes deoxygenated blood from the kidneys via the renal vein and the liver via the hepatic vein. The hepatic portal vein acts as a transport vessel for deoxygenated blood from the digestive tract through the liver and then to the hepatic vein for further transport, but does not directly connect with the inferior vena cava.
