question_answer 27)

  From the following relationships between respiratory volume and capacities, mark the correct option. (i) Inspiratory Capacity (IC) = Tidal Volume + Residual Volume (ii) Vital Capacity (VC) = Tidal Volume (TV) + Inspiratory Reserve Volume (IRV) + Expiratory Reserve Volume (ERV). (iii) Residual Volume (RV) = Vital Capacity (VC) - Inspiratory Reserve Volume (IRV) (iv)Tidal Volume (TV) = Inspiratory Capacity (1C) - Inspiratory Reserve Volume (IRV) Codes (a)(i) Incorrect, (ii) Incorrect, (iii) Incorrect, (iv) Correct (b) (i) Incorrect, (ii) Correct/ (iii) Incorrect, (iv) Correct (c) (i) Correct, (ii) Correct, (iii) Incorrect, (iv) Correct (d)(i) Correct, (ii) Incorrect, (iii) Correct, (iv) Incorrect

Answer:

                  (b)  (i) Inspiratory Capacity (IC) = Tidal Volume + Inspiratory Reserve Volume (TV+ IRV). (ii)Vital Capacity (VC) Tidal Volume + Inspiratory Reserve Volume + Expiratory Reserve Volume. (TV+ERV+IRV)                       (iii) Residual Volume (RV) Volume of air remaining in the lungs after a forcible expiration,                                      Tidal Volume (TV) Volume of air inspired or expired during a normal respiration.
