What is its effect on pulmonary function? Emphysema causes alveolar dilation and destruction of alveolar walls which causes an increase in residual volume with air that cannot be exhaled. Why do we need so many alveoli? Clinical studies indicate that minute ventilation starts increasing exponentially once arterial PO2 is reduced to 60 mmHg. This air cannot be expelled and it helps keep the alveoli (the small air sacs that make up the lungs) open at all times. (b) What happens to your joints without exercise?

After reviewing the discussion of the respiratory cycle, explain why this change forcefully expels air out the nose and mouth.
Does Total Lung Capacity Change During Exercise? "Emphysema results in increased compliance of the lungs, so that it does not generate enough recoil, making it difficult for the lungs to return to resting volume. b. Coughing is the respiratory system's attempt to clear itself of the thick mucus that is produced in response. The heart is therefore transporting oxygen and removing carbon dioxide at a reasonably steady rate via the blood. Exercise results in many adaptations to the cardiovascular system.
