Nutritional requirement- iron
13.deficiency in the amount of oxygen reaching the tissues.
14.a.kidneys
b.Bone marrow
c.Erythropoietin is produced in the kidneys. It circulates in the plasma and induces red cell production in the bone marrow, where it binds to erythroid progenitor cells.
d.Hypoxia
e.Their would be lack of red cell production.
