Match List I with List II : List I (Respiratory Volume) List II (Capacity in mL) A. ERV (Expiratory Reserve Volume) I. 2500 - 3000 mL B. RV (Residual Volume) II. 500 mL C. IRV (Inspiratory Reserve Volume) III. 1000 - 1100 mL D. TV (Tidal Volume) IV. 1100 - 1200 mL Choose the correct answer from the options given below :
A. A-III, B-IV, C-I, D-II
Tidal Volume (TV) is the volume of air inspired or expired during normal respiration, which is approximately 500 mL. Thus, D matches II. Inspiratory Reserve Volume (IRV) is the additional volume of air a person can inspire by a forcible inspiration, averaging 2500 - 3000 mL. Thus, C matches I. Expiratory Reserve Volume (ERV) is the additional volume of air a person can expire by a forcible expiration, averaging 1000 - 1100 mL. Thus, A matches III. Residual Volume (RV) is the volume of air remaining in the lungs even after a forcible expiration, averaging 1100 - 1200 mL. Thus, B matches IV. The correct matching is A-III, B-IV, C-I, D-II. Answer: A-III, B-IV, C-I, D-II
