Aged, abnormal, or damaged red blood cells Macrophage in spleen or liver 1 In macrophages, the globin part of hemoglobin is broken down to individual amino acids (red arrow) and metabolized or used to build new proteins. Hemoglobin 120 days in general circulation Heme Globin 1 Iron Amino acids 2 The heme of hemoglobin releases iron. The heme is converted into bilirubin. 2 Bilirubin Red blood cells 3 Blood transports iron to the red bone marrow, where it is used to produce new hemoglobin (green arrows). Red blood cell production 4 3 Bilirubin in blood Iron 4 Blood transports bilirubin (blue arrows) to the liver. Spleen 5 Bilirubin is excreted as part of the bile into the small intestine. Some bilirubin derivatives contribute to the color of feces. Liver 6 Other bilirubin derivatives are reabsorbed from the intestine into the blood and excreted from the kidneys in the urine.

ADP Thromboxane 3 Platelet 1 Platelet adhesion occurs when von Willebrand factor connects exposed collagen to platelets. Granules 2 Fibrinogen Endothelial cell 1 von Willebrand factor Fibrinogen receptor 2 During the platelet release reaction, ADP, thromboxanes, and other chemicals are released and activate other platelets. Collagen 3 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. Blood vessel wall Platelet plug Smooth muscle cell

Copyright © McGraw-Hill Education. Permission required for reproduction or display. Stage 1 Inactive clotting factors 1 Inactive clotting factors in the plasma are activated by exposure to connective tissue or by chemicals released from tissues. Through a series of reactions, the activated clotting factors form prothrombinase. Connective tissue exposed; chemicals released Calcium and platelet chemicals Injury to vessel 1 Active clotting factors Prothrombinase Stage 2 2 Prothrombinase converts prothrombin to thrombin. Prothrombin Thrombin 2 Stage 3 3 Thrombin converts fibrinogen to fibrin (the clot). Fibrin (clot) Fibrinogen 3

Copyright © McGraw-Hill Education. Permission required for reproduction or display. (a) No agglutination reaction. Type A blood donated to a type A recipient does not cause an agglutination reaction because the anti-B antibodies in the recipient do not combine with the type A antigens on the red blood cells in the donated blood. + Anti-B antibody in type A blood of recipient Antigen and antibody do not match. Type A blood of donor No agglutination (b) Agglutination reaction. Type A blood donated to a type B recipient causes an agglutination reaction because the anti-A antibodies in the recipient combine with the type A antigens on the red blood cells in the donated blood. + Anti-A antibody in type B blood of recipient Antigen and antibody match.

Fig Copyright © McGraw-Hill Education. Permission required for reproduction or display. Fetal Rh-positive red blood cell in maternal circulation Maternal blood Placenta Placental tissue 1 1 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. Fetal blood in capillary Fetal Rh-positive red blood cell Maternal blood is separated from fetal blood by the chorion. First Pregnancy Anti-Rh antibodies 2 2 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. 3 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. Maternal blood 3 4 Fetal blood in capillary 4 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. Subsequent Pregnancy
