Breathing and Exchange of Gases

Match List I with List II.

List I List II
A. Expiratory capacity I. Expiratory reserve volume + Tidal volume + Inspiratory reserve volume
B. Functional residual capacity II. Tidal volume + Expiratory reserve volume
C. Vital capacity III. Tidal volume + Inspiratory reserve volume
D. Inspiratory capacity IV. Expiratory reserve volume + Residual volume

Choose the correct answer from the options given below:

  1. A.A-III, B-II, C-IV, D-I
  2. B.A-II, B-I, C-IV, D-III
  3. C.A-I, B-III, C-II, D-IV
  4. D.A-II, B-IV, C-I, D-III✓

Solution

Expiratory capacity =TV+ERV= \mathrm{TV + ERV} (II); functional residual capacity =ERV+RV= \mathrm{ERV + RV} (IV); vital capacity =ERV+TV+IRV= \mathrm{ERV + TV + IRV} (I); inspiratory capacity =TV+IRV= \mathrm{TV + IRV} (III).
