Ferritin stores are present in the following sites except

Inside the mucosal cell, the ferric iron is formed and is complexed with apoferritin to form ferritin. It is kept temporarily in the mucosal cell. If there is anemia, the iron is fuher absorbed into the bloodstream. If transferrin is saturated with iron, any iron accumulated in the mucosal cell is lost when the cell is desquamated. The fraction of iron absorbed and retained is decided by the iron status. When iron is in excess, absorption is reduced; this is the basis of "mucosal blockRef: DM Vasudevan, page no: 423
