The liver receives approximately 30 of resting cardiac output and is therefore a very vascular organ.

Vascular anatomy of liver. This is the dominant blood supply to the liver parenchyma and allows the liver to perform its gut related functions such as detoxification. The hepatic veins drain the liver into the inferior vena cava. Confusion surrounds the nomenclature of liver anatomy.

The hepatic vascular system is dynamic meaning that it has considerable ability to both store and release blood it functions as a reservoir within the general circulation. It is pinkish brown in color with a soft consistency and is highly vascular and easily friable. The hepatic artery which is oxygen rich supplies the rest.

Venous drainage of the liver is achieved through hepatic veins. The liver has the general shape of a prism or wedge with its base to the right and its apex to the left see the image below. Overview of vascular disorders of the liver.

The hepatic artery and portal vein furnish a double blood supply and venous drainage is handled by the hepatic veins 1920. Hepatic portal vein 75 supplies the liver with partially deoxygenated blood carrying nutrients absorbed from the small intestine. Using vascular ultrasound can help physicians diagnose and review the outcome of treatments for various liver related problems and diseases.

When portal vein blood flow increases. The portal vein which is rich in nutrients and relatively high in oxygen provides two thirds of blood flow to the liver.
