The structure that has a large surface area and therefore increases contact between inspired air and mucosa is the:
 
  a. nose. c. larynx.
  b. carina. d. epiglottis.

Question 2

A large humidity deficit will cause:
 
  a. a nonproductive cough. c. increased move-ment of mucus.
  b. increased cilia func-tion. d. decreased airway resistance.

Answer to Question 1

ANS: A
In the nose, the tortuous path of the turbinates increases contact between the inspired air and the mucosa.

Answer to Question 2

ANS: A
When the airways are exposed to dry, cold air, ciliary motility is reduced; the airways become more irritable; and because mucous production is increased, pulmonary secretions become thick and inspissated, with increased airway resistance and a nonproductive cough.
