The portal vein (PV) delivers 75% of the blood supply to the liver, transporting toxins and nutrients from the gut for processing (1, 2). Although the PV transports partially deoxygenated blood, it is responsible for approximately 50% of the oxygen supply to the liver, with the remainder being supplied by the hepatic artery (3).
The hepatic portal vein is a major vessel in the body that carries blood from the gastrointestinal tract, pancreas, spleen, and gallbladder to the liver for filtration and nutrient processing. It is a critical component of the portal venous system. Location.
