  1. Which leukocycle will stain with basic dyes
    basophils
  2. which leukocyte will stain with acidic dyes
    eosinophils
  3. which leukocyte will stain with neutral dyes
    neutrophils
  4. which leukocyte will produce histamine and heprin? and what r those functions
    basophil HEPRINanticolagulant HISAMINE inflammation and allergies vasodialator
  5. what leukocyte will be the 1st to responf to a diesase
    neutrophil
  6. which wbc will secrete lysomal enzymes(digestive enzymes
    neutrol phils
  7. what wbc forms pus
    neutrophil from dead neutrofragments and dead bacteria
  8. which leukocyte will increase during an allergic reaction?
    esinophils
  9. which wbc will be involved in antibody immunity
    lymphocytes
  10. which wbc will decrease inflammation and what compounds
    eosinophils using hisamines
  11. what wbc wbc will leave blood and become macrophage
    monocyte
  12. what wbc will attract fibroblasts
    monocytes(helps isolate the infection
  13. antigen presenting cell
    monocytes
  14. what leukocyte would perform immunological surveillence
    nk lymphonocyte
  15. wbc invoved in cellular immunity
    lymphocyte t cells
  16. what wbc will fight parasitic infections?
    eosinophils
  17. what wbc will be elevated in someone with a cronic infection
    monocyte
  18. which wbc will attack antigen antibody complexes
    neutrophils
  19. which wbc will cause repiratory burst?
    neutrophil (produceh202 and attacks membrane of cell
  20. how do lymphatic capularies differ from blood capillaries
    are a dead end vessel. endothelial cells overlap.basement membrane incomplete r none exsistant.larger diameter.thinner walls.one way flow. lower resistance -lots of valves musclar compressin respiratory pump
  21. pressure in lymph and intersitual
    • If pressure in the intersitual fluid >pressure In capillary cells separate and fluid comes in. that fluid becomes lymph.
    • If pressure intestitial<capillary pressure,cells do not separate-nothing comes in
  22. lacteal
    is a lymphatic capillary that absorbs dietary fats in the villi of the small intestine.
  23. how lymphatic capillaries merge into large lymphatic vessels
  24. The trunks merge into 1) right lymphatic duct 2)thoratic duct*old lymph back to venous circulation*(as we are doing this we r making new lymph) the excess 3 liters from the venous system goes to the lympatic system causing lymph.
  25. what is the purpose of lympatic ducts?
    • 1)filter looking for pathogens
    • 2proliferation of lymphocytes
