Normally, ​ (a)   taken up by ​ (b)   precursors is either ​ (c)   into heme within the RBC ​ (d)   .

• most iron
• erythroid
• incorporated
• mitochondria or stored

Which of these is not iron storage for Ferritin?

• protein that stores iron in the short-term

• allows iron to be readily available for erythropoiesis

• controls amount of iron released for cellular activity

• fat that stores iron in the long-term

• found in the BM, liver, spleen-stains with Perl's Prussian Blue (specific for Fe)

Match the following descriptions.

• Serum levels reflect tissue storage; caution: APR! (Acid Phase Reactant)

• Sideroblastic Anemia

• long-term storage for iron; iron released more slowly

• Anemia of chronic disease

• microcytic, hypochromic, anisocytosis, poikilocytosi

• Ferritin

• normocytic, normochromic in long-standing cases can be microcytic, hypochromic

• Iron deficiency anemia

• dual population of normochromic and hypochromic erythrocytes

• Hemosiderin

Match the following pictures to their correct description.

• Prussian blue stain reveals ringed sideroblasts

• 
• stains with Prussian blue

• 
• Koilonychia (concavity of nails)

• 
• yellow to brown refractile inclusions

• 
• Glossitis

• 

BM and liver macrophages primarily contain___.

• hemosiderin

• inclusions

• vitamin C

• Gloittis

For Iron Balance Daily absorption and loss are ​ (a)  

Lose ~1 mg per day

​ (b)   of RBCs are destroyed each day

Releases ​ (c)   of iron but most is recycled

Daily requirement for iron is​ (d)  

No physiologic route for ​ (e)   excess iron

• small
• 20-25 mL
• 20-30 mg
• 1 mg
• excreting

Reorder the following Daily iron cycle.

• To maintain iron balance, a similar amount of iron is absorbed from the duodenum.

• Only a small amount of iron is lost from the body through loss of iron-containing cells.

• Macrophages release iron as needed to the developing erythroid cells in the bone marrow.

• Most iron is recycled from the erythrocytes to macrophages in the bone marrow.
