Which vessel provides arterial blood to the liver?

Explanation:
The liver’s arterial blood supply comes from the hepatic artery, which carries oxygen-rich blood to hepatocytes. While the liver also receives a large amount of blood via the portal vein (venous, nutrient-rich blood from the GI tract), that vessel is not arterial. The inferior vena cava carries systemic venous blood back to the heart, not to the liver as an arterial supply. The inferior mesenteric artery supplies the large intestine, not the liver. Therefore, the hepatic artery is the vessel that provides arterial blood to the liver.
