Question

Quizplus · Accepted Answer

The inspiratory reserve volume (IRV) is defined as the amount of air that can be inhaled forcibly over the tidal volume.

Answer: A
 The vital capacity (VC) is the maximum amount of air a person can exhale after taking the deepest breath possible, and it includes the tidal volume, inspiratory reserve volume, and expiratory reserve volume.

Answer: C
 The expiratory reserve volume (ERV) is the amount of air that can be exhaled forcibly over the tidal volume after a normal exhalation.

Answer: F
 The tidal volume (TV) is the amount of air that enters or leaves the lungs during normal breathing at rest.

Answer: E
 The residual volume (RV) is the amount of air that remains in the lungs after a maximal exhalation, and it cannot be voluntarily exhaled.

Answer: B
 The dead space volume (DSV) is the portion of the tidal volume that does not participate in gas exchange because it remains in the airways. It includes the volume of the nose, mouth, trachea, bronchi, and bronchioles.
