Ans.2)The IRV acts as a reservoir of extra lung volume that can become inflated with air as we need it, such as when there is a demand for more oxygen inhalation and CO2 exhalation during exercise . Explain the muscle action associated with an increase in the volume of the thoracic cavity during inspiration. Expiratory reserve volume is the maximum amount of additional air that can be forced out of the lungs after a normal breath. d irv .

Asthma does not affect lung volumes so VC will not be affected, Bronchodilator drugs open up airways and clear mucus. Why is it that blood flowing through the chambers within the heart cannot supply sufficient oxygen or remove enough carbon dioxide from the myocardium? Explain what happens to the muscles. The PR and RT intervals remained virtually unchanged with the PR intervals remaining the same both before and after exercise with an interval time of 0.15 seconds, and the RT interval increase by 0.01 seconds from 0.37 at rest to 0.38 seconds after exercise. A decrease in the persons resting heart rate means they are able to recover quicker after an activity. A number of factors affect the normal predicted lung volumes and capacities, including _________, ________, _______ and _____________. How does exercise affect the respiration rate?
