HNF 150            Fall 2007 P Thurston Lecture Notes C. Deficiency: the thyroid gland enlarges-goiter to compensate for lack of  iodine D. Toxicity: also can result in the enlargement of the gland III.  Iron A. Function: oxygen-carrying cells. . hemoglobin-red blood cells,  myobloben-muscle cells, body recyles iron, lose iron through blood  loss, elps many enzymes use oxygen needed to make new cells,  amino acids, hormones, and neurotransmitters  B. Deficiency: C. Recommendations: men (18+):         8mg/day women (19-50): 18 mg/day pregnant women27 mg/day upper limit is 45mg/day hemogrotosis-too much iron-darker pigmentation D.
