From the following relationships between respiratory volumes 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 (IC) – Inspiratory Reserve Volume (IRV)
(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
