The hepatic portal system is the system of veins in the liver that comprises the hepatic portal vein and its tributaries. It is a venous portal system in which the portal vein receives blood via its tributaries from the capillaries of most of the abdominal viscera and drain it into the hepatic sinusoids. The veins of the hepatic portal circulation drain the digestive organs, spleen, and pancreas and deliver the blood to the liver via hepatic portal vein. As blood percolates through the liver, some of the nutrients are stored or processed in various ways for release to the general circulation. The liver in turn is drained by the hepatic veins that enter the inferior vena cava.

Anything pertaining to the liver is called hepatic.
