Which vessel is primarily responsible for delivering oxygen to the liver?

Explanation:
Oxygen delivery to the liver comes mainly from the arterial supply. The portal vein brings most of the blood flow to the liver, but it carries relatively deoxygenated blood from the gut, so it isn’t the primary source of oxygen. Oxygen-rich blood travels through the hepatic artery and reaches hepatocytes via the liver’s sinusoids, providing the majority of the tissue’s oxygen. The hepatic veins drain blood away from the liver to the inferior vena cava and do not deliver oxygen.
