Question

Quizplus · Accepted Answer

The inspiratory reserve volume is the extra volume of air that can be maximally inspired over and above the tidal volume.

Answer: A 
 The vital capacity is the maximum amount of air that can be forcibly exhaled after a maximal inspiration. It includes the tidal volume, inspiratory reserve volume, and expiratory reserve volume.

Answer: E 
 The residual volume is the volume of air that remains in the lungs after maximal expiration. It cannot be measured directly by spirometry.

Answer: L 
 The inspiratory capacity is the maximum volume of air that can be inspired from the end-expiratory level. It includes the tidal volume and inspiratory reserve volume.

Answer: F 
 The total lung capacity is the total volume of air in the lungs after maximal inspiration.

Answer: G 
 The functional residual capacity is the volume of air remaining in the lungs at the end of a normal expiration. It includes the expiratory reserve volume and residual volume.

Answer: M 
 The anatomic dead space volume is the volume of air that fills the conducting airways and does not participate in gas exchange.

Note: 
- Respiratory rate, FEV1, pulmonary ventilation, and alveolar ventilation are not lung volumes or capacities.
