Answer to Question 1

ANS: B
One-half to two-thirds of total airway resistance occurs in the nose, not the bronchi, the oral pharynx, or the diaphragm.

Answer to Question 2

ANS: A
Parasympathetic innervations for the lung are via the vagus nerve. Parasympathetic innervations of the lung are not associated with the phrenic, brachial, or pectoral nerves.
