Regarding respiratory volumes and capacities: How can minimal volume serve as both a medical and legal tool? There will be more capillaries present so the quicker the oxygen will get to the muscles. In untrained persons, cardiac output increases in response to exercise primarily by an increase in heart rate. Why is it that blood flowing through the chambers within the heart cannot supply sufficient oxygen or remove enough carbon dioxide from the myocardium? Expiratory reserve volume decreased with exercise because greater respiratory effort forced more air out of the lungs with each exhalation. What was the purpose of the nose clip? During exercise, tidal volume increases as the depth of breathing increases and the rate of breathing increases too.
