How to Get into Venture Capital: Venture Capital Recruiting Did tidal volume change between rest and exercise? What is pneumothorax and how does it develop? When you are exercising aerobically, your muscles consume more oxygen and produce more carbon dioxide than they do at rest. 6 How is the expiratory reserve volume related to tidal volume? 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 . 6. Minute ventilation is the total volume of air inhaled and exhaled each minute.
