If RBCs are more than 9um, they are __. | macrocytic |
Normally, __ percent of RBCs are lost per day. | 1 |
What 3 things is RBC production dependent upon? | Iron, B12, Folic Acid |
If erythropoiesis is effective, __ percent of progenitor cells will become RBCs. | 90 |
If erythropoiesis is ineffective, __ percent of progenitor cells will be destroyed in the bone marrow or immediately after release. | 10 |
Decreased total and effective erythropoiesis is called __ __. | aplastic anemia |

Microcytic, hypochromic anemia can be caused by these 6 things: | 1) abnormality of HGB synthesis 2) Iron deficiency (in 90% cases) 3) Deficiency of heme synthesis (sideroblastic anemia) 4) Chronic disease 5) Deficiency of globin synthesis (thalassemias) 6) Iron level insufficient |
Macrocytic, normochromic anemias are caused by these 6 things: | 1) B12 or folate def 2) alcoholism 3) ovalocytes or tear drop cells 4) megaloblasts or NRBCs 5) Def. in DNA production (all cells affected) 6) Liver disease (symptoms include chronic hemolytic anemia, high retic count) |
