During embryonic and fetal development, hematopoiesis occurs in all of the following except: Yolk sac Lymph nodes Liver Spleen AGM Cell type derived from common myeloid progenitor (CMP): T cell Neutrophil B cell NK cell Plasma cell Abnormal RBC inclusions that contain iron deposits, visible with Prussian blue and Wright's stain are called: Pappenheimer bodies Howell-Jolly bodies Cabot rings ZPP Basophilic stippling Which of the following statements is true regarding AIDS? Severe immune deficiency results from the progressive loss of CD4+ T cells At advanced stages of the disease the CD4:CD8 ratio is about 2:1 Leukopenia affects only T cells, all other leukocyte levels remain normal All of the above are true Which of the following does not apply to the genetic alteration that underlies sickle cell anemia? The resulting HbS has an altered charge that affects its solubility The alteration affects the mobility of HbS in an electrophoresis gel The overall quantity of HbS is significantly reduced Under conditions of low oxygen, the HbS will aggregate Polycythemia vera is an MPD. results in elevated hematocrit levels. is frequently associated with genetic alterations in JAK2. can be treated by therapeutic phlebotomy. All of the above are true about PV.
Immature red blood cells called erythroblasts eject their nuclei, allowing the cells to contain more hemoglobin, the molecule that transports oxygen.
