2. Arterial supply The liver receives a dual blood supply from the portal vein and  hepatic arteries .

3. The hepatic portal vein supplies ~75% of the liver's blood supply by volume and carries venous blood drained from the spleen, gastrointestinal tract, and its associated organs ( hence oxygen-poor and nutrient-rich ). The hepatic arteries supply arterial blood to the liver and account for the remainder of its blood flow ( hence oxygen-rich and nutrient-poor ). Oxygen is provided from both sources; approximately half of the liver's oxygen demand is met by the hepatic portal vein, and half is met by the hepatic arteries.

5. Venous D rainage Most of the venous drainage from the liver passes into the three hepatic veins (Right h epatic vein, Middle hepatic vein and Left hepatic vein)  which drain into the inferior vena cava.
