The controlled variable included the exercise bike and heart rate monitor. Inspiratory reserve volume decreased with exercise because a faster breathing rate emptied the lungs and prevented full inspiration. Please explain what oxygen, glucose and ATP have to do with this. Why do bodybuilders have sagging muscles when they stop working out? So not only is the heart filled with more blood to eject, it expels a greater percentage of the end-diastolic volume. Since cholesterol is used to make bile, increasing bile production would What is vital capacity and how do you calculate it? carbon dioxide and pH affect minute ventilation. Why is a higher heart rate during the recovery period equated with a lower level of fitness? If so, explain why this number changes. During exercise, tidal volume increases as the depth of breathing increases and the rate of breathing increases too. a. After a small period of rest, the heart rate and breathing rate both decreased to a point close to their resting rate. So TV increases, Hypothesize what might happen to the reserve volumes (IRV and ERV) when you exercise. a. irv is the amount of air that can be inhaled after a normal inspiration. 9.During exercise, the depth of respiration increases. My Zoom files didn't convert. systemic capillaries carbon dioxide diffuses into the capillaries resulting in a decrease in pH. What does it mean when one person is more "in shape" their body is more efficient at delivering oxygen to the muscles. Explain why the atria have thinner walls than the ventricles of the heart. Explain why the contraction of the diaphragm and intercostal muscles causes a decrease in intrathoracic pressure. The measurements of respiration rate, pulse rate and blood pressures were noted as described in Harris-Haller (2016). So,ERV(Expiratory Reserve volume) decreases. 9.During exercise, the depth of respiration increases.
