Answer to Question 1

ANS: B
Terminal bronchioles are the smallest conducting airways and function to supply gas to the res-piratory zone of the lung.

Answer to Question 2

ANS: D
With loss of consciousness, the head flexes forward, which can partially or completely obstruct the upper airway (Figure 9-41, A). Extension of the head and lower jaw into the sniff position alleviates this obstruction (Figure 9-41, C). Extension of the head moves the tongue away from the rear of the pharynx. This technique is used to maintain the airway in unconscious patients and facilitates placement of artificial airways.
