  2. structures of the lower reapiratory tract
  3. what cells line the respiratory tract?
    pseudostratifies collumnar cillA
  4. what does goblet cells do and what does cilla do

    Normally carres food or drink but if it carries air you burp*after this it eneter the esophagus*
  13. what does the auditory tube open into?
    nasopharynx(to equalize pressure)
  14. what does the palate prevent
    food from enetering our nasal cavity
  15. what does the epiglottis prevent

  16. what cartilage are single
  17. cartilage in larynx is for what

  23. what happens when you move deeper in lungs
    the passage becomes deeper and deeper with every branching.diameter becomes smaller and smaller and surface area increases. the deeper you get less cartilage and more smooth muscle.

  25. visceral pleural bound

  29. what do type 1 avelolar cells do
    reduce olural effusion
  30. type 2 aveolar cells
    produce serfactant
  31. what are the layers in order that oxygen does thru regarding the aveloi
    surfacient,type 1 aveolar cells,basement membrane,intersitial space,capilary,endothelium of capillary
