Question

Maximum expiratory volume is

• A. 100 ml
• B. 1100 ml
• C. 1500 ml
• D. 3000 ml

Answer 1

Answer: (B)

1100 ml

Expiratory reserve volume is the maximal volume of air that can be exhaled from the end-expiratory position. This is the difference between the volume of air left in the lung at the conclusion of normal expiration versus at the conclusion of maximal expiration. Expiratory reserve volume is about 1.1 litres or 1100 ml.
