The liver is the largest solid organ in the body and has dual blood supply from the hepatic artery and portal vein, draining into the vena cava.

“so i mean the liver is the largest solid organ in the body it has some interesting anatomical nuances it has a dual blood supply so it's supplied by the hepatic artery which is a major branch essentially off the aorta as well as the portal vein which is the blood drainage of all of the intestinal blood flow and the reason that returns through the liver is the liver is the filter essentially the metabolic filter for the the metabolites absorbed in the gi tract it then lives on top of the vena cava the major vein returning blood from the lower part of the body back to the heart and actually sits right below the diaphragm right below the right atrium where it has this complex venous network that drains into the vena cava”
