THE CARDIOVASCULAR SYSTEM: BLOOD
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.
blood cells are studied in terms of RBC anatomy, physiology, life cycle, and
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.
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.
chapter concludes with medical terminology associated with blood.
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
