GENERAL HISTOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -The hepatic portal vein receives blood specifically from the stomach, intestines, pancreas, and spleen, and carries it into the liver through the porta hepatis. The porta hepatis serves as the point of entry for the hepatic portal vein and the proper hepatic artery, and is the point of exit for the bile passages.

Detailed explanation-3: -The portal vein (PV) is the main vessel of the PVS, resulting from the confluence of the splenic and superior mesenteric veins, and drains directly into the liver, contributing to approximately 75% of its blood flow [1]. Hepatic artery provides the remaining hepatic blood flow.
