Final answer:
Excess iron stored in hemosiderin protects the body against anemia. Hemosiderin is a protein-containing storage form of iron found in the bone marrow, liver, and spleen. It acts as an internal iron reserve to prevent sudden iron loss from bleeding.
Step-by-step explanation:
Excess iron is stored in hemosiderin to protect the body against anemia. Hemosiderin is a protein-containing storage form of iron found in the bone marrow, liver, and spleen. It acts as an internal iron reserve to prevent sudden iron loss from bleeding. Ferritin, another iron storage protein, is also present in these tissues.
Iron plays various important roles in the body, including the transport of oxygen to tissues, involvement in cellular respiration, and being an essential component of hemoglobin and respiratory enzyme systems. When iron is administered parenterally in excess of the body's capacity to store it, it accumulates as hemosiderin in the liver.
