The liver’s job with blood from the gut is to extract nutrients for use, storage, or conversion. After absorption, the portal vein delivers nutrient‑rich blood to the liver, where glucose, amino acids, fatty acids, vitamins, and minerals are taken up and processed into glycogen, plasma proteins, lipoproteins, or other metabolites. This handling of nutrients from the blood is a central hepatic function, so describing what the liver removes from blood as nutrients captures its main role.

Oxygen is carried to tissues and isn’t something the liver primarily removes from blood; urea is produced in the liver as a waste product to be excreted by the kidneys, not removed from blood by the liver; glucose is indeed a nutrient the liver uses and stores, but the broader and more encompassing description of the liver’s action on portal blood is its extraction and processing of nutrients.
