    • A. transports
    • B. temp. maintenance
    • C. fluid balance
    • D. acid-base balance
    • E. hemostasis
    • F. resistance
  3. Define plasma?
    fluid portion of unclotted whole blood
  4. Define serum?
    fluid portion of clotted whole blood
  5. Define erythrocyte?
    red blood cells
  6. Define leukocyte?
    white blood cells
  7. Define thrombocyte?
    platelets
  8. What is the function of erythrocytes?
    transport O2 (hemoglobin)
  9. What is the function of neutrophils?
    phagotype > promotes inflamation
  10. What is the function of eosinophils?
    phagotype > anti-inflamatory
  11. What is the function of basophils?
    phagotype > inflamatory
  12. What are the functions of momocytes/macrophages?
    phagocytosis, immunity, inflamatory
  13. What is the function of lymphocytes?
    immunity
  14. What is the function of thrombocytes?
    hemostasis
  15. Define erythropoiesis?
    RBC production
  16. Outline erythropoieses's regulation?
    hypoxia > kidney > erythropoietin > red marrow > RBCs
  17. What are the required dietary factors of erythrocytes?
    • 1. nutritional- iron, amino acids, folic acids, B12
    • 2. intrinsic factor- made by stomach B12- absorption (sm int.)
  18. Where is intrinsic factor produced and what is it's function?
    stomach, B12 absorption (sm int.)
  19. What are the blood types of the ABO group?
    A, B, AB, O
  20. Which antigens and antibodies are associated with each type?
    • A > A, anti B
    • B > B, anti A
    • AB > both antigens, no antibodies
    • O > no antigens, both antibodies
  21. What is unique about ABO group antibodies?
    naturally occuring
  22. What is responsible for most transfusion reactions?
    recipient's antibodies targeting donor's antigens
  23. Identify the universal donor and recipient and explain why each qualifies?
    • O-, no RBC antigens to be targeted
    • AB+, no antibodies to target RBCs
  24. How are people classified with regard to the Rh D antigen?
    • + > has
    • - > doesn't
  25. Outline the general setting in which antibodies against the Rh D antigen would produce?
    antibodies can be formed by a Rh neg person if exposed to Rh D antigens on the RBCs of a Rh+ person
  26. Define hemostasis?
    stoppage and bleeding
  27. List the sequence of events involved in hemostasis?
    • 1. vascular spasm
    • 2. platelet plug
    • 3. coagulation
  28. Define coagulation?
    cascading series of reactions d/t clotting factors > fibrin clot
