Erythropoietin

Erythropoietin is a hormone produced mainly by the kidneys that stimulates the production of red blood cells in the bone marrow. Red blood cells are essential for carrying oxygen from the lungs to the rest of the body. When oxygen levels in the blood are low, the kidneys release more erythropoietin to increase red blood cell production. Conversely, when oxygen levels are adequate, less erythropoietin is produced. This regulation helps maintain healthy oxygen delivery and overall balance in the blood, playing a crucial role in the body's response to conditions like anemia or low oxygen environments.
