So,ERV(Expiratory Reserve volume) decreases. Ans.2)The IRV acts as a reservoir of extra lung volume that can become inflated with air as we need it, such as when there is a demand for more oxygen inhalation and CO2 exhalation during exercise . Therefore with exercise , there is a decrease in IRV as ...
