Chapter 19 THE CARDIOVASCULAR SYSTEM: BLOOD Chapter Synopsis This chapter begins with a discussion of the functions of blood, followed by the physical characteristics of blood. The components of blood are then discussed. The formation of blood cells is followed by the study of the blood cells. Red blood cells are studied in terms of RBC anatomy, physiology, life cycle, and erythropoiesis. White blood cells are studied in terms of WBC anatomy and types (granular and agranular) and physiology. Platelets lead into the process of hemostasis with vascular spasm, platelet plug formation, clotting, fibrinolysis, hemostatic control mechanisms, and intravascular clotting all included. Clotting is discussed in terms of the intrinsic and extrinsic pathways, steps to the formation of prothrombinase, the common pathway, clot retraction and repair, and the need for vitamin K. Blood groups and types are discussed, as is hemolytic disease of the newborn, transfusions, and typing and cross-matching blood for transfusion. Homeostatic imbalances discussed include anemia, sickle- cell disease, hemophilia, disseminated intravascular clotting, and leukemia. The chapter concludes with medical terminology associated with blood. Clinical applications discussed include withdrawing blood, induced polycythemia, iron overload and tissue damage, medical uses of growth factors, reticulocyte count, bone marrow transplant, complete blood count, anticoagulants, and aspirin and thrombolytic agents.
