Blood of the hepatic portal artery is an oxygenated blood. The liver receives arterial blood, carrying oxygen, from the hepatic artery.
All of the blood which passes through the intestine and spleen is delivered to the liver by the hepatic portal vein for detoxification.
Blood flow to the liver is unique in that it receives both oxygenated and deoxygenated blood. As a result, portal blood has lower pO2 and perfusion pressure than the other organs of the body. Blood passes from branches of the portal vein through cavities between "plates" of hepatocytes called sinusoids. Blood also flows from branches of the hepatic artery and mixes into the sinusoids to supply the hepatocytes with oxygen. This mixture percolates through the sinusoids and collects in a central vein which drains into the hepatic vein. The hepatic vein subsequently drains into the inferior vena cava and goes through oxygenation process involving the lungs..

Artery = oxygenated. Vein = de-oxygenated. Therefore, hepatic portal artery is oxygenated blood surely?

Im not doctor, but i would say that it was oxygenated, but i might be wrong.
From my school days a long time ago, i thought that the only de-oxygenated artery was the pulmonary artery leading from the heart to the lungs. And the only oxygenated vein being the pulmonary vein leading from the lungs back to the heart.

The only oxygen filled blood in a vein is the Pulmonary vein and the pulmonary artery carries de-oxygenated blood. All other arteries carry oxygenated blood.

Blood in the hepatic portal artery is oxygenated, which originates from the left ventricle via the aorta and its branches.

The answer is oxygenated, there is only one artery in the human body that carries deoxygenated blood and that is the pulmonary artery.

Arteries only carry oxygenated blood.

It is oxygenated because of the side of the heart it lays I'd say

I have to say that there is no portal artery, IT'S A VEIN!!! It's deoxygenated!!
