Red blood cell (RBC) production (erythropoiesis) takes place in the bone marrow under the control of the hormone erythropoietin (EPO). Juxtaglomerular cells in the kidney produce erythropoietin in response to decreased oxygen delivery (as in anemia and hypoxia) or increased levels of androgens. How can RBC be controlled? If you have a high RBC count: …
