| hemolytic anemia | decreased survival of mature erythrocytes and inability of bone marrow to compensate for the decreased life span |
| aplastic anemia | bone marrow suppression with replacement of the hematopoietic cells by fat |
| iron deficiency anemia | inadequate iron results in no hemoglobin synthesis |
| pernicious anemia | deficiency of V. B12 preventing stem cell division in bone marrow |
| thalassemia | inability to produce adequate amounts of normal protein subunits of hemoglobin |
| sickle cell anemia | mutation of amino acid sequence upon releasing bound O2 they sickle which can cause blockage |
