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.
