Original Khojo Papers practice question — not from a past board paper.
Answer
Tidal volume is the volume of air inspired or expired in a normal breath, about 500 mL. Vital capacity is the maximum volume that can be expired after a maximum inspiration. Residual volume is the air remaining in the lungs after the most forceful expiration, about 1,100 to 1,200 mL.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Total lung capacity is the vital capacity plus the residual volume.
