Show Answers:

  1. The sticky mucous in the membrane lining of the nasal cavity is secreted by
    the globlet cells
  2. The force that causes air to move into the lungs during inspiration is supplied by
    atmospheric pressure
  3. The peripheral chemoreceptors in the carotid and aortic bodies are most sensitive to changes in blood
    oxygen ion concentration
  4. The amount of air that enters or leaves the lungs during normal respiratory cycle is the
    tidal volume
  5. The vocal cords are located within the
  6. The condition of newborns called respiratory distress syndrome is caused by a
    lack of surfactant
  7. The respiratory membrane consists of
    two thicknesses of epithelial cells and basement membranes
  8. The amount of oxygen released from oxyhemoglobin increases when
    carbon dioxide concentration increases
  9. The enzyme carbonic anhydrase cause
    carbon dioxide to react with water
  10. Which of these layngeal cartilages occur singly rather than in pairs?
  11. The pitch of a vocal sound is controlled by changing the
    tension in the vocal cord
  12. The walls of the alveoli are composed of
    simple squamous epithelium
  13. Which of the following bones does not possess sinuses?
  14. The force responsible for normal expiration is supplied by the
    elastic recoil of tissues and surface tension
  15. The portion of the respiratory center that is responsible for establishing the basic pattern of breathing is the
    ventral respiratory group
  16. The visceral and parietal pleural membranes are normally held together by
    surface tension created by the serous fluid
  17. The intensity (volume) of a vocal sound is the result of the
    force of air passing over the vocal cords
  18. Additional muscles required for deep inspiration are
    the pectoralis minors and sternocleidomastoids
  19. During laughing
    deep breathing is released in a series of short expirations
  20. The central chemoreceptors in the medulla oblongata are most sensitive to changes in blood
    hydrogen ions concentration
  21. The movement of air into and out of the lungs is explained by Boyle's law, which implies:
    If volume increases, the pressure decreases
  22. The maximum volume of air that can be exhaled after taking the deepest breath is called
    vital capacity
  23. An inflation reflex (Breuer reflex) helps regulate the depth of breathing which
    prevents over inflation of the lungs during forceful breathing
  24. Carbon Dioxide is mostly 70% transported
    as bicarbonate in carbolic acid
  25. During sneezing:
    deep breathing is taken in; air is forced against closed glottis and directed into the nose
