While the liver is technically1 part of the gastrointestinal system, it also plays an important role in blood circulation. The liver has been called the antechamber of the heart because it collects and processes all of the gastrointestinal blood through the portal vein2 and delivers it to the right side of the heart. The liver receives blood through two vascular3 systems, the portal vein and hepatic artery4.
