Name the process of red blood cell production, the hormone that controls it, the source of that hormone, and the stimulus for its production. Why was the hormone so difficult to isolate and identify?
What will be an ideal response?
Production of red blood cells is called erythropoeisis. It is stimulated by the kidney-produced hormone erythropoietin, in response to hypoxia. It was difficult to isolate and identify because it is made on demand rather than stored, and thus is not present all the time.
