The volume of air involved in breathing movements can be estimated by using a spirometer which helps in clinical assessment of pulmonary functions, which option correct for respiratory volumes and capacities ?
(i) Additional volume of air, a person can expire by a forcible expiration is expiratory reserve volume.
(ii) Additional volume of air, a person can inspire by a forcible inspiration is inspiratory reserve volume.
(iii) Volume of air remaining in the lungs even after a forcible expiration is residual volume.
(iv) Total volume of air a person can inspire after a normal expiration is IRV.
(v) Total volume of air a person can expire after a normal inspiration is ERV.
(vi) Volume of air that will remain in the lungs after a normal expiration is functional residual capacity.
(vii) The maximum volume of air a person can breathe in after a forced expiration is vital capacity
