Answer to Question 1

The body has a feedback system that monitors blood iron levels. When the iron levels are in the right range or a little bit too high, the liver produces and secretes hepcidin, which reduces iron absorption from the body. When blood iron levels are low, hepcidin secretion from the liver is reduced so that the body will absorb more iron from food.
