Detailed explanation-1: -The hepatic portal vein brings the absorbed nutrients from the stomach, small intestine and the large intestine to the liver.

Detailed explanation-2: -The portal vein carries blood and nutrients from the intestine and delivers them to the liver cells (hepatocytes), which perform specific liver functions.

Detailed explanation-3: -The hepatic portal vein is formed by the confluence of three main vessels, the gastric, pancreaticomesenteric, and lienomesenteric veins.

Detailed explanation-4: -The liver receives blood from two sources: the hepatic portal vein (70%), and the hepatic arteries (30%). The hepatic portal vein receives blood specifically from the stomach, intestines, pancreas, and spleen, and carries it into the liver through the porta hepatis.

Detailed explanation-5: -The hepatic portal vein carries blood from the intestine to the liver before it is delivered to the systemic circulation. It carries the nutrient-rich blood to the liver which is further processed there and returned back to the heart via inferior vena cava.
