Answer to Question 1

ANS: C
During inspiration, gas fills the balloon and closes a hole in the expiratory valve. Closing of the hole makes the patient circuit a sealed system. During expiration, the balloon deflates, the hole opens, and gas from the patient is exhaled into the room through the hole.

Answer to Question 2

ANS: C
The external exhalation valve is represented by the letter C in the figure. B is pointing to the expiratory line. The main inspiratory line is represented by the letter A. The expiratory valve line is represented by D.
