How does the body know how to adjust the level of iron absorption to match its needs?

Question 2

You suspect that your new college roommate may have an eating disorder because, although she seems to have a normal body size, you have heard her frequently vomiting after a meal, and her tooth enamel is becoming corroded.

 a. anorexia nervosa.
 b. bulimia nervosa.
 c. binge eating disorder.
 d. the female athlete triad.

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.
