Erythropoiesis: The Roles of Erythropoietin and Iron

A feedback loop involving erythropoietin helps regulate the process of erythropoiesis so that, in non-disease states, the production of red blood cells is equal to the destruction of red blood cells and the red blood cell number is sufficient to sustain adequate tissue oxygen levels but not so high as to cause sludging, thrombosis, or stroke. Erythropoietin is produced in the kidney and liver in response to low oxygen levels. In addition, erythropoietin is bound by circulating red blood cell… WebErythropoiesis is the medical term for the process of producing new red blood cells. In this stage, your bone marrow makes red blood cells without enough hemoglobin.
