To describe:
The life cycle of a red blood cell from production through destruction.
Introduction:
The life cycle of a red blood cell involves the formation and differentiation of these cells in the bone marrow. They are formed from the hematopoietic stem cells by the secretion of the growth factors. The mature red bloods transport in the blood vessels and carry oxygen.
The old red blood cells are phagocytosed by the macrophages in the liver. The hemoglobin is degraded into heme and protein part globin. The heme contains the porphyrin ring, which is degraded into biliverdin and bilirubin. They are present in bile and reach the
