Document Summary

Iron is essential for the production of red blood cells; we will talk about the uptake and recirculation of iron. Red blood cells circulate in the blood for about 120 days before they are engulfed by the macrophages. Section: factor essential for red blood cell production, regulation of rbc production by erythropoietin, uptake and recirculation of iron, recycling iron from old/damage rbc"s, absorption of vitamin b12. Factor essential for red blood cell production: cytokine, erythropoietin (epo): key regulator that stimulate red blood cell synthesis, dietary factors, iron: synthesis of hemoglobin in the development of red blood cell. Increased in epo will increase production of red blood cell by the bone marrow. Increasing the capacity of the blood and returning oxygen level to normal. Iron is important for the production of red blood cell: diet is good source for iron, consumed and absorbe from the intestine to blood.
