Answer to Question 1

ANS: D
The upper airway is responsible for humidifying inspired air. The upper airways add heat and humidity to inspired gases during inhalation. The nasal mucosa is kept moist by secretions from the mucous glands. Humidity and warmth are captured by the nasal mucosa, and exhaled air is cooled.

Answer to Question 2

ANS: D
15/17.5  100 = 85.
