Becаuse it is difficult tо excrete irоn оnce it is in the body, iron bаlаnce is maintained primarily through absorption. The iron storage protein ________________ captures surplus iron from food and stores it in the mucosal cells of the small intestine. When the body needs iron, the storage protein releases some iron to an iron transport protein called ________________ . If the body does not need iron, the dietary iron is carried out when the intestinal cells are shed (every three to five days) and excreted in the feces.
