Is it possible for a subject to have a vital capacity within normal range but a value of FEV1 below normal range? Explain how inhaling increased amounts of CO2 affects pulmonary ventilation. This means that VC = TLC - RV. a. 1. What is the significant function of the residual volume? Explain why/why not, No. Vital capacity is the maximum amount of air that can be breathed out after breathing in as much air as possible. A persons venous return increases due to the higher cardiac output. Inspiratory capacity increased with exercise because of the greater amount of air that could be moved, due to greater tidal volumes. Answer and Explanation: 1. Lung volumes and exercise. (Chile, Bolivia, el Per, el Paraguay), Neruda uses various metaphors to characterize Whitman's poems. Assuming that an individual's TLC does not change, 1.
