QUESTION 9

1. The volume that describes air volume moved during either the inspiratory or expiratory phase of each breathing cycle is the:

   	A.	Inspiratory reserve volume
   	B.	Forced vital capacity
   	C.	Residual volume
   	D.	Tidal volume question 9

Answer 1

D. Tidal volume.

Tidal volume is known as the volume of air that a person inspires or even expires at the rest in normal breathing pattern. So the volume that describes air volume moved during either the inspiratory or expiratory phase of each breathing cycle is the tidal volume.

A. The volume of air that describes the maximum effort of air that inspired which is more than the tidal volume is known as the Inspiratory reserve volume. So it is not the suitable answer.

B. The amount of air that describes the maximum effort of air that is exhaled from the lungs from the deepest breath is known as the forced vital capacity, so it is not the suitable answer.

C. The volume of air that describes the air that is remained in the lungs after having a force expiration is known as the Residual volume, so it is not the suitable answer.
