Question

Does the hepatic portal system provide the liver with oxygenated blood?

Answer 1

A portal system never carries oxygenated blood.

Hepatic artery delivers oxygenated blood to liver.

Explanation:

Liver receives both oxygenated and deoxygenated blood.

• Oxygenated blood is delivered by a short hepatic artery which is a branch of celiac artery. (Latter is generally called celiac trunk, and it sends branches to liver, stomach, spleen.)

• Deoxygenated blood comes along hepatic portal vein. The blood is drained from various parts of gastrointestinal tract including wall of small intestine.

The hepatic portal section brings in absorbed nutrients from gut to liver. Portal vein arises inside one organ (in this case gut wall,etc) and enters another (in this case liver) without returning to heart.
