Answer to Question 1

ANS: A
Approximately 70 of total body iron is found in hemoglobin. Another 25 is stored as ferritin or hemosiderin in macrophages, and about 5 is found in myoglobin. The remainder is found primarily in iron-containing enzymes. A small amount is bound to iron for transport.

Answer to Question 2

ANS: B
Infants and young children need more iron to support an expanding erythron.

This occurs without any major symptoms until the high blood pressure becomes extreme. Regular blood pressure checks are an important method of catching hypertension before it can kill you.
