Question: As exercise intensity increases, the respiratory system increases oxygen delivery to the body via the lungs by up to 10 to 20-fold. Answer the following questions to help you understand how this increase in oxygen delivery occurs A. What are simple ways to increase ventilation to the lungs (i.e. change minute ventilation)?B. How can the volume of oxygen delivery to the blood be increased without increasing lung ventilation?C. Describe how the following factors alveolar ventilation. Dead space Airway resistance Compliance (or lack thereof) of the lung/chestD. Given these effects, which of the following two strategies would be best for increasing alveolar ventilation: Larger tidal volumes Higher breathing frequency Explain.E. Based on your answers to questions A and C, form a hypothesis for how you think respiration will change at the onset of exercise in order to increase alveolar ventilation. Briefly explain why.
