Select the Statement That Best Describes How Iron Reaches the Tissues

Select the statement that best describes how iron reaches the tissues and cells in the body.

A) The plasma protein manufactured by the liver that delivers iron to tissues is called transferrin. It reversibly binds two ferric ions (Fe⁺⁺) absorbed from the intestine and macrophage activity and delivers them to other tissues.
B) The plasma protein manufactured by the liver that delivers iron to tissues is called intrinsic factor. It reversibly binds two ferric ions (Fe⁺⁺) absorbed from the intestine and macrophage activity and delivers them to other tissues.
C) The plasma protein manufactured by the liver that delivers iron to tissues is called folic acid. It reversibly binds two ferric ions (Fe⁺⁺) absorbed from the intestine and macrophage activity and delivers them to other tissues.
D) None of these are correct.
