What is a liver portal vein?

liver portal vein is the main blood vessel in the abdomen, acts as a collection point for blood from the digestive tract and points this blood into the liver. Almost all blood passing through the digestive tract ends in the liver portal vein before spreading back into the body, allowing the liver to filter blood and remove toxins and begin metabolizing substances absorbed through the gastrointestinal tract. It is important to realize that despite the name, this structure is not a real vein in an anatomical sense, because blood does not return to the heart. Many smaller blood vessels act as tributaries to feed the hepatic portal vein, including splenic vein and superior mesenteric veins. This container connects and creates a short, strong hepatic portal vein and the veins have been divided and fed blood into the vario -American regions of the liver for processing. Blood drains from the liver through the liver vein and this blood will be cleaned because it has already undergone metabolism in the liver.
