What is the hepatic portal circulation?
Another name for the hepatic portal system is the portal venous system. The purpose of hepatic portal circulation is to deliver blood from some parts of the gastrointestinal tract to the liver. In other words, blood is drained from the digestive organs (and the spleen, gall bladder, and pancreas) and the blood is then delivered to the liver. The vein that is used for this process is the hepatic portal vein.
The hepatic portal vein also transports other things to the liver as well. It transports absorbed nutrients, white blood cells from the spleen, poisonous substances that were absorbed in the intestines, and waste products.
The hepatic portal vein and its tributaries comprise the hepatic portal system. It is also called the portal venous system which directs blood from different parts of the Gastro-intestinal tract to the liver. Hepatic portal circulation is mainly responsible for blood to be available for helping in the digestive process. The hepatic portal vein, located in the right upper abdomen, carries blood from the GI tract and the spleen to the liver, and this allows the liver to process the nutrients taken from the digestive system. Hepatic portal circulation helps the liver to eliminate the Toxins and convert glycogen to glucose, that provides energy.
