cardiovascular system- blood: ERYTHROPOIESIS

Question 1

production of erythrocytes

Answer 1

erythropoiesis

Question 2

erythropoiesis
step 1: red bone marrow—->

Answer 2

myeloid tissue stem cells—-> proerythroblasts—-> erythroblasts (synthesize hemoglobin) —> reticulocyte

Question 3

erythropoiesis
step 2: reticulocytes enter

Answer 3

the blood stream and mature to form erythrocytes

Question 4

production of leukocytes

Answer 4

leukopoiesis

Question 5

leukopoiesis
red bone marrow. pleuripotential stem cells or hemocytoblasts

Answer 5

myeloblasts
lymphoblasts
monoblasts

Question 6

leukopoiesis
promyelcytes —>

Answer 6

CSF, IL5, IL4

Question 7

leukopoiesis
promyelcytes–> CSF

Answer 7

neutrophil myelocytes—> neutrophilic band cells —> enter blood stream–> neutrophil

Question 8

leucopoiesis
promyelcytes–> IL5

Answer 8

eosinophil myelocytes—> eosinophilic band cells–> enter blood stream–> eosinophil

Question 9

leucopoiesis
promyelcytes–> IL4

Answer 9

basophil myelocytes—> basophilic band cells—> enter blood stream–> basophil

Question 10

production of thrombocytes

Answer 10

thrombocytopoiesis

Question 11

thrombocytopoiesis
pleuripotent stem cells in the red bone marrow–>

Answer 11

megakaryoblasts–> megakaryocytes (form membranes, enzymes, proteins) –> thrombocytes (by shedding cytoplasm)
