Explain, physiologically, the relationship between how much weight a muscle can lift and the reason a muscle reaches a point of isometric contraction. Dependent Variable. Explain why these adaptions are beneficial. Why does exercise increase a need for blood supply? 5. Describe how lung volume affects pressure and therefore air movement. 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 . Lung volumes are the volume of gas in the lungs at a given time during the respiratory cycle and include tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume. Then, draw an arrow from each adverb to the word or words it modifies. A.Nothing, we could easily fill them up when we inhaled again B.The alveoli would collapse C.The trachea would. Which change in gas levels activates breathing and prevents you from holding your breath forever? exercise does not change the amount of air your lungs can hold. Due to the increase in blood flow, vasoconstriction of arterioles occurs to maintain mean arterial pressure (Bassett & Edward, 1997).

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?
