regions structures of the repiratory tract

  1. what ar the structures of the respirator tract
    nose nasal cavity pharynx
  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
    goblet cells make mucus to lubricate & moistine airways

    CILIA( movement) propel mucus up and down your airways cough things up
  5. what does the nasal cavity do acting as an air passage way
    so you can eat and breath at the same time
  6. how does the nasal cavity deal with speaking
    when you speak the sound waves bounce off the nasal cavity creating sound*reason why you sound different when yoour sick because of snot*
  7. why does the nasal cavity filter and clean air
    so it doesnt travel down into your lungs
  8. how does your nasal cavity warm and humidify air
    before entering your lungs using blood vessels to warm air and humidifies before it hits lungs
  9. how does the olfacton work with hunger sensations
    it sences the small and relates to taste and hunger sensations
  10. what does the nasopharynx do
    equals pressure in our ears
  11. what is the purpose of the oropharnyx
    its a passage for resp. and digest it carries air and drink.(the palate elevates and closes off the opening of the nasal pharynx preventing drink from coming out of your nose.)
  12. what does the laryngopharyx 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
    food from entering our lungs
  16. what cartilage are single
  17. cartilage in larynx is for what
  18. what cartilage are paired
    arytenoid,coiniculade,and cuneiform are paired
  19. how many c shaped cartilage are in the trachea
    15 to 20 to support traches
  20. tracheotomy
    horizontal incision between cartilages that provide temp airway
  21. tracheostomy
    vertical incision into airway that is permanent
  22. how does the bronchial tree run
    trachea runs into primary bronchi then splits to secondary bronchi with 3 on the right and 2 on the left. split into tiarancy and there is one tiarancy for each segment of lung 10 on right 9 on left.
  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.
  24. where is the pleural cavity bound
    to wall of thoracic cavity
  25. visceral pleural bound
    bound to lungs surface
  26. whhat is the pleural space
    in the middle of pleural cavity containing pleural fluid decreasing friction
  27. what is pleurosy
    when chest cavity runs against wall(mostly viral or bacterial infection)
  28. what is perlural infusion
    to much fluid lungs are unable to properly inflate
  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
