-liverCorrectAs RBCs are broken down, the heme of their hemoglobin is split off from globin. Its core of iron is salvaged and stored for reuse. The balance of the heme group is degraded to bilirubin, a yellow pigment that is released into the blood. Liver cells pick up the bilirubin and in turn secrete it (in bile) into the intestine, where it is metabolized to urobilinogen. Most of this degraded pigment leaves the body in feces, as a brown pigment called stercobilin.

-B-negative female pregnant with an AB-positive babyCorrectHemolytic disease of the newborn (HDN) can develop when an Rh-negative mother carries an Rh-positive fetus. Unlike anti-A and anti-B antibodies, anti-Rh antibodies are not preformed (i.e., a person doesn't produce them until they've been exposed to Rh-antigens for the first time). This initial exposure can occur when the Rh-negative mother carries her first Rh-positive baby. The first such pregnancy usually results in the delivery of a healthy baby. But during this pregnancy and particularly during delivery, the mother may be sensitized by her baby's Rh-positive antigens that pass into her bloodstream. If so, she will form anti-Rh antibodies unless treated with RhoGAM during pregnancy and around the time of delivery. RhoGAM is a serum containing anti-Rh antibodies. By agglutinating the Rh factor, it blocks the mother's immune response and prevents her sensitization. If the mother is not treated and becomes pregnant again with another Rh-positive baby, her antibodies will cross through the placenta and destroy the baby's RBCs, producing the condition known as hemolytic disease of the newborn (HDN).

-sickle-cell anemiaCorrectIn sickle-cell anemia, the havoc caused by the abnormal hemoglobin, hemoglobin S (HbS), results from a change in just one of the 146 amino acids in a beta chain of the globin molecule. This alteration causes the beta chains to link together under low-oxygen conditions, forming stiff rods so that HbS becomes spiky and sharp. This, in turn, causes the red blood cells to become crescent shaped when they unload oxygen molecules or when the oxygen content of the blood is lower than normal. The stiff, deformed RBCs rupture easily and tend to jam up in small blood vessels. These events interfere with oxygen delivery, leaving the victims gasping for air and in extreme pain. Bone and chest pain are particularly severe, and infection and stroke often follow.
