What is the term for red blood cell formation?

• A. Erythropoietin
• B. Erythropoiesis
• C. Hematopoietin
• D. Leukopoiesis

Answer: (B)

Red blood cell formation is called erythropoiesis. It happens in the bone marrow as stem cells commit to the erythroid lineage and mature through stages into circulating red blood cells. This process is driven by erythropoietin, a hormone produced by the kidneys in response to low oxygen levels; it signals the bone marrow to increase red cell production to improve oxygen delivery. For contrast, erythropoietin is the stimulating hormone, not the process itself, while hematopoiesis is the general formation of all blood cells and leukopoiesis specifically refers to white blood cell production.
