    Plasma
  2. a red blood cell
    Erythrocyte
  3. a white blood cell
    Leukocyte
  4. a platelet, involved
    in blood clotting
    Thrombocytes
  5. an inability of the blood to carry sufficient oxygen to the tissues
    Anemia
  6. a laboratory test to
    determine the total volume of the red blood cells
    Hematocrit or sed rate
  7. used to determine the types of “antigens” located on the red blood cell to facilitate blood
    transfusions
    Blood typing
  8. blood minus its cells
    plasma
  9. where are RBC formed
    red bone marrow
  10. what is the RBC structure
    • disk-shaped,
    • without nuclei
  11. what is the function of RBC
    transport oxygen and carbon dioxide
  12. anemia is caused by
    •Inadequate RBC numbers

    •Deficiency of hemoglobin

  16. abnormally high WBC count
    Leukocytosis
  17. produce antibodies
    Lymphocytes
  18. protect against parasitic irritants that cause allergies
    Eosinophils
  19. produce heparin, which inhibits clotting
    Basophils
  20. stages of clotting
    • cut in vessel
    • prothrombin released
    • Prothrombin activator and calcium convert prothrombin to thrombin
    • Thrombin triggers formation of fibrin, which traps RBCs to form a clot
  21. substance that can activate immune system
    Antigen
  22. substance made by body in response to stimulation by an antigen
    Antibody
  23. Rh factor antigen present in RBCs
    Rh-positive blood
  24. Rh factor antigen absent in RBCs
    Rh-negative blood
  25. ˜may occur when Rh-negative mother
    carries a second Rh-positive fetus; caused by mother’s Rh antibodies reacting
    with baby’s Rh-positive cells
    Erythroblastosis fetalis
