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. Spleen Iron 1 2 3 4 5 6

Chemical mediators also increase capillary permeability, and fluid leaves the capillaries, producing swelling (arrows). A splinter in the skin causes damage and introduces bacteria. Chemical mediators of inflammation are released or activated in injured tissues and adjacent blood vessels. Some blood vessels rupture, causing bleeding. White blood cells (e.g., neutrophils) leave the dilated blood vessels and move to the site of bacterial infection, where they begin to phagocytize bacteria and other debris.

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.

Fetal Rh-positive red blood cell Fetal blood in capillary Placental tissue Subsequent Pregnancy Fetal blood in capillary Maternal blood 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, if Rh-positive red blood cells cross the placenta and enter the maternal circulation, they can 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. 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.
