Quizplus · Accepted Answer

Iron is recycled from RBCs and stored in the body as ferritin, a protein that stores iron in a non-toxic form. Bilirubin is a waste product from the breakdown of heme in RBCs, hemoglobin is the protein in RBCs that carries oxygen, and hematocrit is a measure of the percentage of RBCs in the blood. Therefore, the correct choice is B. Iron released from the breakdown of hemoglobin in dying RBCs is stored in the liver as ferritin, a protein that binds and stores iron for later use. Bilirubin is a waste product of heme breakdown that is excreted in bile. Hemoglobin is the oxygen-carrying protein in RBCs, and hematocrit is a measure of the volume of packed red blood cells in a given sample of blood.
