Red blood cells originate in the red bone marrow inside large bones such as the femur. Bone marrow is stimulated to produce these cells by a hormone called erythropoietin, which is produced by the kidney as old red blood cells dies. The whole process takes about a week, and interestingly, mature red blood cells have no nuclei.
