What is the difference between the hepatic artery hepatic vein and hepatic portal vein?
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. The blood flows through the liver tissue to the hepatic cells where many metabolic functions take place.
What is hepatic artery and portal vein?
The portal vein and hepatic arteries form the liver’s dual blood supply. Approximately 75% of hepatic blood flow is derived from the portal vein, while the remainder is from the hepatic arteries. Unlike most veins, the portal vein does not drain into the heart.

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.
Why hepatic portal vein is deoxygenated?
1 Answer. Because the blood is first pumped from the heart to the intestines, where the oxygen is released and used. the blood cells also pick up the digested food from the digestion process and then travel to the liver.
Is hepatic vein and portal vein the same?

What is the hepatic vein?
Hepatic veins are blood vessels that return low-oxygen blood from your liver back to the heart. The veins are key players in the supply chain that moves the blood that delivers nutrients and oxygen to every cell in your body. A blockage in one of the hepatic veins may damage your liver.
What is the purpose of portal vein?
The portal vein (PV) is the main vessel of the portal venous system (PVS), which drains the blood from the gastrointestinal tract, gallbladder, pancreas, and spleen to the liver.
