Questions and Answers Graded A+
Where do all RBCs originate? - Correct answer-Red Bone Marrow - flat and
irregular bones (ribs, vertebrae, sternum, pelvis)
Where is the most common site for bone marrow aspiration? - Correct answer-Iliac
Crest
Hematopoiesis - Correct answer-Process of blood cells developing from stem cells
Hematopoietic Stem Cells - Correct answer-precursor cells
Immature Form - Correct answer-Blasts
Mature Form - Correct answer-Cyte
What are the two cell lines that form from the progenitor stem cell? - Correct
answer-Myeloid and Lymphoid Line
Dyscrasia - Correct answer-any abnormal condition of the blood
Myeloid Line - Correct answer-RBC, Megacryocyte, Monocytes, Neutrophils,

, Lymphoid Line - Correct answer-T and B Lymphocytes
Erythropoietin - Correct answer-hormone excreted by the kidney to stimulate the
production of RBCs in response to tissue hypoxia
What raw materials does RBC production/maturation depend on? - Correct answer-
Amino Acids, Iron, Vitamin B12, Vitamin B6, and Folic Acid
What is the lifespan of a RBC - Correct answer-115-120 days; succumbs to
phagocytosis by the spleen or liver
Anemia - Correct answer-reduction in the total number of erythrocytes or a
decrease in the quality/quantity of hemoglobin
What are the causes of anemia? - Correct answer-Impaired erythrocyte production
Acute or chronic blood loss
Increased erythrocyte destruction
Combination of the above
How is anemia classified? - Correct answer-- based on MCV: micro-, normo-, or
macro-cytic
- based on cause: factor deficient, hemolysis, blood loss
- hemoglobin content (chromic)
