Question

Quizplus · Accepted Answer

Regulation of iron entering the body occurs mainly through absorption of dietary iron into the enterocyte. The absorption of iron from the intestine into the blood is tightly regulated to maintain optimal iron levels in the body. The absorption of dietary iron is controlled by the hormone hepcidin, which regulates the expression of the iron transporter proteins in the enterocyte. Hepcidin helps to prevent excessive iron accumulation and also regulates the release of iron from iron-storing cells in the body. Chelation of dietary iron in the intestine and excretion of excess iron from the intestine into the urine are secondary mechanisms of iron regulation.
