• C. i. 500 ml ii. 3,000 ml iii. 1,200 ml iv. 1,200 ml
• D. i. 500 ml ii. 1,200 ml iii. 3,000 ml iv. 1,200 ml

Answer 1

The correct option is C

i. 500 ml ii. 3,000 ml iii. 1,200 ml iv. 1,200 ml

500 ml is the volume of air that you take in during normal inspiration, or breathe out during normal expiration. This is called tidal volume (TV). The additional volume of air a person can inspire, beyond the tidal volume by putting in extra effort (inspiratory reserve volume) is 3,000 ml. The additional volume a person can expire, beyond the tidal volume, that is after normal expiration (expiratory reserve volume) is normally 1,200 ml. The residual volume is normally 1,200 ml.
