The liver has a dual blood supply, receiving most of its blood flow (75%) as deoxygenated blood from the portal vein, and the rest from the hepatic artery. The portal vein is a low-pressure system of valveless vessels which does not autoregulate according to hepatic oxygen demand, but rather according to supply (eg. with meals, the portal vein dilates and increases its flow). The main vessel of the hepatic portal system is the hepatic portal vein (Figures 3.31 and 3.32), a large vein that lies in the gastrohepatoduodenal ligament alongside the hepatic artery and anterior part of the bile duct.The hepatic portal vein is formed by the confluence of three main vessels, the gastric, pancreaticomesenteric, and lienomesenteric veins.

'Hepatic' means of or relating to the liver, therefore the ... Portal Circulation. The portal venous system drains the intestines, pancreas, and spleen with numerous collateral anastomoses to other venous beds of the abdomen. There is a mixing of portal and systemic blood circulation within the sinusoids, and all the blood eventually drains from the liver via the hepatic veins to the inferior vena cava. Oxygenated blood flows in from the hepatic artery. Nutrient-rich blood flows in from the hepatic portal vein. The liver holds about one pint (13%) of the body's blood supply at any given moment. The liver consists of 2 main lobes. Both are made up of 8 segments that consist of 1,000 lobules (small lobes). Of the total hepatic blood flow (100-130 ml/min per 100 g of liver, 30 ml/min per kilogram of body weight), one fifth to one third is supplied by the hepatic artery. About two thirds of the hepatic blood supply is portal venous blood. The gross vascular supply of the liver is conceptually described in Figures 2.1 and 2.2.
