Guys why are red blood cells formed in the bone marrow?

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. In addition to erythropoietin, red blood cell production requires adequate supplies of substrates, mainly iron, vitamin B12, folate, and heme.

Explanation:

In the red bone marrow there are stem cells called hemocytoblasts that give rise to all of the former elements in the blood

Explanation: i hope this helped! (Sorry if I’m wrong)
