The heme of hemoglobin releases iron. The heme is converted into bilirubin. Blood transports iron to the red bone marrow, where it is used to produce new hemoglobin (green arrows). Blood transports bilirubin (blue arrows) to the liver. Bilirubin is excreted as part of the bile into the small intestine. Some bilirubin derivatives contribute to the color of feces. Other bilirubin derivatives are reabsorbed from the intestine into the blood and excreted from the kidneys in the urine.

During the platelet release reaction, ADP, thromboxanes, and other chemicals are released and activate other platelets. Platelet aggregation occurs when fibrinogen receptors on activated platelets bind to fibrinogen, connecting the platelets to one another. The accumulating mass of platelets forms a platelet plug. 3 1 2 3 1 ADP Thromboxane Platelet Granules von Willebrand factor Collagen Platelet plug Smooth muscle cell Endothelial cell Blood vessel wall Fibrinogen receptor 2

Before or during delivery, Rh- positive red blood cells from the fetus enter the blood of an Rh= negative woman through a tear in the placenta. The mother is sensitized to the Rh antigen and produces anti-Rh antibodies. Because this usually happens after delivery, the fetus is not affected in the first pregnancy. During a subsequent pregnancy with an Rh-positive fetus, Rh-positive red blood cells cross the placenta, enter the maternal circulation, and stimulate the mother to produce antibodies against the Rh antigen. Antibody production is rapid because the mother has been sensitized to the Rh antigen. The anti-Rh antibodies from the mother cross the placenta, causing agglutination and hemolysis of fetal red blood cells, and hemolytic disease of the newborn (HDN) develops. 1 1 2 3 4 2 3 4 Maternal circulation Maternal Rh-negative red blood cell Anti-Rh antibodies Maternal circulation Maternal Rh-negative red blood cell Fetal Rh-positive red blood cell in the maternal circulation Maternal circulation Maternal anti-Rh antibodies cross the placenta.
