Detailed explanation-1: -Blood leaves the liver through the hepatic veins. This blood is a mixture of blood from the hepatic artery and from the portal vein. The hepatic veins carry blood to the inferior vena cava-the largest vein in the body-which then carries blood from the abdomen and lower parts of the body to the right side of the heart.

Detailed explanation-2: -The blood drains out of the liver via the hepatic vein. The liver tissue is not vascularised with a capillary network as with most other organs, but consists of blood filled sinusoids surrounding the hepatic cells.

Detailed explanation-3: -The liver has two blood supplies, the hepatic artery and the portal vein. The hepatic artery provides oxygen and nutrition, while the portal vein delivers substances absorbed by the gastrointestinal tract for metabolic conversion and/or removal.
