Detailed explanation-1: -All of the blood supply to the vertebrate intestine returns to the heart via the liver. This arrangement permits immediate processing of absorbed nutrients by the liver and allows the liver to act as a critical metabolic barrier for any toxicants that may have entered the intestinal blood along with nutrients.
Detailed explanation-2: -Why does nutrient-rich blood of the hepatic portal vein pass first through the liver before this blood is returned to the heart? To allow the liver to store or modify the nutrients.
