In addition to erythropoietin, red blood cell ...
NettetEach red blood cell has a life span of around 100–120 days. Old, dead, or damaged red blood cells are engulfed by phagocytic cells in the liver, spleen, and lymph nodes. The iron from these cells is subsequently recycled to produce new hemoglobin. 2. Red blood cells produce a protein called hemoglobin, which helps them carry out their primary ...
