What happens to the iron portion of the heme of a phagocytized red blood cell?
*The iron attaches to TRANSFERRIN (a plasma protein) and is transferred to one of the three following places:
1. Most (~60%) of the iron is taken to the LIVER where the the transferrin passes it off to APOFERRITIN (apoferritin + iron = FERRITIN). The iron is stored in liver as ferritin.
2. To the SPLEEN, stored as ferritin
3. To the BONE MARROW to make hemoglobin
