Question

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:

• A. A-II, B-IV, C-I, D-III
• B. A-III, B-II, C-IV, D-I
• C. A-II, B-I, C-IV, D-III
• D. A-I, B-III, C-II, D-IV

Answer 1

The Correct Option is A

To correlate List I with List II, the definitions of respiratory volumes and capacities are provided:

• Expiratory Capacity (EC): The total volume of air exhaled following a normal inhalation. Calculation: Tidal Volume (TV) + Expiratory Reserve Volume (ERV). Match: A-II.
• Functional Residual Capacity (FRC): The volume of air remaining in the lungs post-normal expiration. Calculation: Expiratory Reserve Volume (ERV) + Residual Volume (RV). Match: B-IV.
• Vital Capacity (VC): The maximum volume of air expelled from the lungs after maximum inhalation. Calculation: Expiratory Reserve Volume (ERV) + Tidal Volume (TV) + Inspiratory Reserve Volume (IRV). Match: C-I.
• Inspiratory Capacity (IC): The maximum volume of air inhaled following normal expiration. Calculation: Tidal Volume (TV) + Inspiratory Reserve Volume (IRV). Match: D-III.

The definitive correlation is: A-II, B-IV, C-I, D-III.
