Detailed explanation-1: -The liver’s second blood supply comes via the hepatic artery which delivers highly oxygenated blood from the lungs. Once the liver has deoxygenated and processed this blood, it is transported to the liver’s central hepatic vein. It then leaves the liver and travels up to the heart.
Detailed explanation-2: -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.
Detailed explanation-3: -The liver receives a blood supply from two sources. The first is the hepatic artery which delivers oxygenated blood from the general circulation. The second is the hepatic portal vein delivering deoxygenated blood from the small intestine containing nutrients.
Detailed explanation-4: -The liver is unusual in that it has a double blood supply; the right and left hepatic arteries carry oxygenated blood to the liver, and the portal vein carries venous blood from the GI tract to the liver.
