1. anemia

   • reduction of red cell mass
   • claccifcations
     • related to the size
       • microcytic
         • sidroblastic anemia
           • defect in heme synthesis
         • anemia of chronic diseases
           • inhibits release of iron from stores
         • iron deficiency
           • most common anemia
           • treatment of iron deficiency anemia
             • iron supplements

             • reduced globin chain synthesis
           • sickle cell anemia
             • genetic defect leads to abnormal hemoglobin
           • hereditary spherocytosis
             • genetic defect in genes coding for ankyrin and spectrum
