    process by which WBC can enter tissue spaces
  5. Name 5 Leukocytes
    basophil, eosinophil, neutrophil, lymphocyte, monocyte
  6. Platelets
    • thrombocyte; lifespan: 8-11 days
    • - cell fragment
    • - function in clotting
  7. Hemostasis
    process by which bleeding is stopped
  8. 3 Steps in Hemostasis

  24. LDL Cholesterol
    bad (lousy) cholesterol
  25. HDL Cholesterol
    good (healthy) cholesterol
  26. Uric Acid
    elevated levels indicate gout
  27. BUN (Kidney Function Test)
    Blood, Urea, Nitrogen
  28. Sources of capillary blood
    • 1. fingertip
    • 2. earlobes
    • 3. great toe/heel
