Definition & Meaning of "erythropoietin"

What is "erythropoietin"?

Erythropoietin is a hormone that regulates the production of red blood cells. It is produced primarily in the kidneys in response to low oxygen levels in the blood. Erythropoietin stimulates the bone marrow to increase the production of red blood cells, which carry oxygen throughout the body. This hormone plays a critical role in maintaining adequate oxygen supply to tissues and organs, especially during times of reduced oxygen availability or in conditions such as anemia.
