    • NO
    • PGI2 (prostacyclin)
  2. What is AT-III?
    • made in liver
    • binds to heparin to form heparin-sulfate system
  3. What is heparin-sulfate system?
    binds to thrombin and stops clotting
  4. What is MCV?
    • Mean corpuscular volume
    • (size of RBC)
  5. Bone marrow aspirations are good diagnostic tests for what?
    • certain anemias
    • leukemias
    • plt DO
    • imunoglobulin DO
  6. _______ removes the liquid portion of BM; where ______ removes the solid portion.
    • aspiration
    • biopsy
  7. Newborns have the same number of _____ as they will as adults.

  16. S/S of iron deficiency anemia
    • ridged & coarse nails
    • bald, fissured tongue
  17. Cause of secondary polycythemia.
