Question 1: Describe the changes in ventilation that occur during exercise. Explain how these changes are produced and how they affect arterial blood gases and pH.
Question 2: What are mechanisms that affect ventilation at a high altitude? Explain why the change in ventilation is beneficial and how it can also be detrimental. What other factors operate at a high altitude to improve the oxygen delivery to the tissues?
Question 3: Describe the changes in pulmonary ventilation when the pulmonary arterial blood flow is blocked by an embolus. How this will affect regional expiration of carbon dioxide and uptake of oxygen?
Question 4: Describe the changes in oxygen delivery process to the skeletal muscles during heavy exercising.
