The liver receives two blood supplies; which vessel delivers oxygen-rich arterial blood to the liver?

Explanation:
The liver has two blood supplies: one brings oxygenated arterial blood, and the other brings nutrient-rich venous blood from the GI tract. The vessel that delivers oxygen-rich arterial blood to the liver is the hepatic artery. It provides the oxygen that hepatocytes rely on for metabolic processes. In contrast, the hepatic portal vein delivers blood high in nutrients but relatively low in oxygen from the GI tract, and the hepatic veins carry blood away from the liver into the inferior vena cava. So the hepatic artery is the source of the liver’s arterial, oxygen-rich blood.
