Pulmonary System

  1. How does the air inside the lungs differ than atmospheric air?
    Air inside the lungs have carbon dioxide
  2. The carina of the trachea is found at the level of which vertebra?
    5th thoracic
  3. Touching of the carina leads to ______ reflex
  4. The main difference between the right and left lungs is______.
    Left lung does not have a middle lobe, only superior and inferior. (Because of location of the apex of heart)
  5. The ______ is the functional homologue of the middle lobe of the right lung.
  6. If swallowed a foreign body, the most likely bronchus that it will end up in is the _______ bronchus.
  7. Gas exchange occurs at the _____ zone.
  8. Respiratory bronchioles contain _____ muscle.
  9. True/False: Much like heart does not get the blood that is coming in, the lungs do not get their oxygen from the air pass through.
  10. The lungs DO/DO NOT (pick one) fill the entire pleural space?
    DO NOT
  11. ______gutters are spaces that allows the lung to expands to
  12. Subcostals and transversus thoracic are muscles on the rib cage and their function is to _______
  13. Tertiary bronchi subdivides into ______, part of the ______zone.
    Terminal bronchioles; conducting
  14. The respiratory zone is contained within the ________
  15. Type ____ alveolar cell produces _____ that ____the surface tension.
    II; surfactant; reduces
  16. Laplace’s Law states that tension _____ as radius _____ at the same pressure.
    Increases; increases
  17. True/false: air pressure alone is sufficient to expand lungs
    False; it also requires pleural adhesion of visceral and parietal pleura
  18. When the thoracic wall is punctured, it results in _____.
  19. Loss of _________pressure allows the lungs to recoil and collapse.
    Negative intrapleural
  20. In pneumothorax, inhalation causes the heart to shift ______, whereas exhalation the heart shifts ______.
    Away from the punctured thorax, towards the punctured thorax.
  21. Pulmonary fibrosis is an example of when the lungs have too _____ compliance and _____ elastance. Resulting in stiffness of the lungs and difficulty expanding.
    Low; high
  22. Emphysema is an example when the lungs have too ____ compliance and ______ elastance. The lungs do not recoil properly and air accumulates inside the lungs.
    High; low
  23. In order for the airway to remain open, pressure inside the airway has to be ______ than the pressure outside the airway.
  24. Epinephrine act on _____ receptors and leads to bronchodilation, decreasing airway _____.
    Beta; resistance
