| mixed population of cell colors | polychromasia |
| breakdown of RBCs & release heme proteins into the bloodstream; releases bilirubin & causes icterus | hemolytic anemia |

| two immature RBCs | rubricytes and reticulocytes |
| bone marrow doesn't respond to anemia - no immature RBCs in circulation | non-regenerative anemia |
| three causes of anemia | decreased RBC production, increased RBC destruction, hemorrhage |
