Final answer:
The hepatic portal vein conducts blood from the digestive tract and spleen to the liver as part of the hepatic portal system. The liver processes this blood to remove waste and excess nutrients. The option (C) is correct.
Step-by-step explanation:
The hepatic portal vein is a blood vessel that conducts blood from the digestive tract and spleen to the liver. It is part of the hepatic portal system, which allows the liver to receive blood from two different sources: the normal systemic circulation via the hepatic artery, and the hepatic portal vein that carries blood rich in digested nutrients from the digestive tract.
The liver processes this blood to remove waste and excess nutrients before it exits the liver and flows into the inferior vena cava. Therefore, option (C) is correct.
