  • Trachea
    divides into the right and left mainstem bronchi and continues to divide into smaller
    passages
  • Bronchioles
    terminate into the alveolar ducts and alveoli
  • Alveoli
    is the gas exchanging units in the lungs
  • Larynx
    o warms, filter and humidify
    o helps to make sound
    o sends air to lower airways
  • external respiration
    ▪ the exchange of gases (oxygen and carbon dioxide) between the alveoli and
    the blood through the alveolar-capillary membrane
  • internal
    ▪ the exchange of gases between the systemic capillaries and the tissue at the
    cellular level
  • cellular
    ▪ exchange of gases within the cell

  • Cheyne-Stokes Respiration
    o May result from severe congestive heart failure, drug overdose
  • Biot’s Respiration
    o May be seen with meningitis or severe brain damage
  • Ataxic
    o A more extreme expression of Biot’s respirations indicating respiratory compromise
  • Air Trapping
    o In chronic obstructive pulmonary disease, air is trapped in the lungs during forced
    expiration
