• The portion of the nasal cavity contained within the flexible tissues of the external nose is the . . .

  nasal vestibule
• What aspect of laryngeal function would be impaired if the arytenoid and corniculate cartilages were damaged?

  The larynx would be unable to move up or downward during swallowing to ease the passing of a bolus.
• The cartilage that serves as a base for the larynx is the . . .

  cricoid cartilage
• The vocal folds are located in the . . .

  larynx
• The trachea

  is reinforced with C shaped cartilages
• The cartilage in the walls of the lobar and segmental bronchi . . .

  support the bronchi and assist in keeping the lumens open
• The epithelium of the nasal vestibule . . .

  contains coarse hairs that guard the nasal opening from the entry of large particles and insects
• Why does a person with a cold often have a stuffed-up nose?

  The response of the nasal epithelium to irritants, such as those that cause the common cold, is to secrete greater amounts of mucus than normal to trap the virus particles
• How does deep breathing differ from costal breathing?

  The diaphragm contracts in deep breathing, white it does not contract in costal breathing.
• How many lobes does the right lung have?

  The right lung has three lobes.
• What is bronchodilation?

  Bronchodilation is the enlargement of the airway lumen.
• What is the function of the alveolar macrophages?

  The alveolar macrophages phagocyte particulate matter.
• What is the function of the septa?

  The septa divide the lung into lobules.
• What do the intrinsic laryngeal muscles do?

  One group regulates tension in the vocal folds, and the second group opens and closes the glottis.
• Which paired laryngeal cartilages are involved with the opening and closing of the glottis?

  The paired laryngeal cartilages involved with the opening and closing of the glottis are the corniculate and arytenoid cartilages.
• What portion of the pharynx does the laryngopharynx include?

  The laryngopharynx includes the portion lying between the hyoid bone and the entrance to the esophagus.
