The portal vein delivers what to the liver?

Explanation:
The portal vein is part of the hepatic portal circulation that drains blood from the digestive tract and spleen to the liver. Its main job is to deliver nutrient-rich blood absorbed from digestion—glucose, amino acids, fatty acids, vitamins, and minerals—to the liver. The liver then uses these nutrients for energy, storage (like glycogen), synthesis of proteins, and detoxification. Oxygen, by contrast, comes mainly from the hepatic artery, not the portal vein. Hormones and immune components travel in the bloodstream, but the hallmark function of the portal vein is supplying the liver with nutrients absorbed from the gut.
