All blood cells start off as what? Right Ans - Hemocytoblast
From a hemocytoblast, blood cells are branched off into what 5 cells? Right
Ans - Proerythroblast, myeloblast, lymphoblast, Monoblast, and
Megakaryoblast
Proerythroblast turn into what before becoming erythrocytes (RBCs) Right
Ans - Polychromatic Erythroblast
The myeloblast turns into what next which for which 3 granulocytes? Right
Ans - The myeloblast turns into the progranulocyte which then turns into
Basophil, Eosinophil, and Neutrophil which are all granulocytes.
The Lymphoblast turns into what? Right Ans - Turns into a lymphocyte
which is a agranulocyte which is a leukocyte.
The monoblast will turn into what? Right Ans - Monocyte, which turns into
a agranulocyte which is a type of leukocyte.
What are the 2 types of leukocytes? Right Ans - Granulocytes and
Agranulocytes
What are the 3 types of granulocytes? Right Ans - Basophil, Eosinophil, or
Neutrophil
What are the 2 types of agranulocytes? Right Ans - Lymphocyte and
Monocyte
The megakaryoblast turns into what? Right Ans - a megakaryocyte which
turns into thrombocytes
The hemocytoblast is what type of cell? Right Ans - stim cell
The word blast means what Right Ans - Not a true mature cell
,Stages of forming a RBC: Right Ans - Stem cell--committed cell
(proerythroblast)--Phase 1: Ribosome Synthesis(early erythroblast)----Phase
2: Hemoglobin Accumulation(late erythroblast)---Phase 3: Ejection of
Nucleus(Normoblast)--- then Reticulocyte---then Erythrocyte!
RBCs are carrying what to all of the tissues and providing oxygenation
Right Ans - Hemoglobin
RBCs are very flexible and very what? Right Ans - thin
RBCs have a large surface area for the Right Ans - oxygen- which is bound

Each hemoglobin molecule should have what percentage of saturation?
Right Ans - 95%
Kidneys are producing which hormone for RBC production Right Ans -
erythropoietin
Erythropoietin does what? Right Ans - Released by the kidney to stimulate
