Describe the roll of erythropoietin in erythrocyte production and hemostasis and where it is released from - Answer Erythropoietin is a hormone secreted from the kidneys & liver, and its purpose is to stimulate 'erythrocyte colony forming unit' to transform into a 'erythroblast'. Erythroblast multiply and synthesize hemoglobin. When this is done the nucleus shrivels and leaves the cell, turning it into a 'reticulocyte'. The reticuloctye leaves the bone marrow and after a day or two lo...
