Solution


Q.

Match List I with List II.                                                        [2024]

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

Ans.

(1)

Expiratory Capacity (EC) is the total volume of air a person can expire after a normal inspiration. This includes tidal volume and expiratory reserve volume (TV + ERV).

Functional Residual Capacity (FRC) is the volume of air that will remain in the lungs after a normal expiration. This includes ERV + RV (residual volume).

Vital Capacity (VC) is the maximum volume of air a person can breathe in after a forced expiration. This includes ERV, TV and IRV.

Inspiratory Capacity (IC) is the total volume of air a person can inspire after a normal expiration. This includes tidal volume and inspiratory reserve volume (TV + IRV).
