Question

Arrange the following in the order of increasing volume.
(I) Tidal volume (II) Residual volume
(III) Inspiratory reserve volume (IV) Vital capacity

• A. I < II < III < IV
• B. I < III < II < IV
• C. I < IV < III < II
• D. I < IV < II < III

Answer 1

The correct option is A I < II < III < IV

Tidal volume = 500 mL
Residual volume = 1200 mL
Inspiratory reserve volume = 3100 mL
Vital capacity = 4800 mL
