WebTidal volume (TV) is the volume of air that you breathe in and out during normal breathing (e.g., from 2.5 to 3.5 liters and back to 2.5 liters during one inspiration and expiration), but much larger inspiratory (IRV) and expiratory reserve volumes (ERV) are possible during forced inspiration and WebThe inspiratory reserve volume is the volume of air that can be breathed in beyond the normal tidal volume. This volume decreases with exercise because the tidal volume increases and the lungs have to work harder to bring in enough oxygen to meet the body's needs. The body also uses more oxygen during exercise, so the lungs have to work harder …
