Answer to Question 1

ANS: A
Rapidly adapting irritant receptors in the epithelium of the larger conducting airways have vagal sensory nerve fibers. Their stimulation, whether by inhaled irritants or by mechanical factors, causes reflex bronchoconstriction, coughing, sneezing, tachypnea, and narrowing of the glottis.

Answer to Question 2

ANS: B
In adults, the Hering-Breuer reflex is activated only at large tidal volumes (800 to 1000 ml or more) and, apparently, it is not an important control mechanism in quiet breathing.
