Question

Where are the primary storage sites for iron in the body, and how do these stores affect the onset of deficiency?

Accepted Answer

Liver and bone marrow store iron; adequate stores delay the onset of deficiency because they provide iron for hemoglobin synthesis during short-term dietary shortfalls.

Answer

Pancreas and spleen store elemental iron crystals that are insoluble and gradually dissolve to supply circulating hemoglobin in times of need.

Answer

Kidneys and adipose tissue are the main iron depots; they rapidly release iron on demand and prevent any risk of deficiency regardless of diet.

Answer

Skin and hair follicles hold most iron as ferritin and immediately release it during stress, which is the primary mechanism preventing anemia in adults.
