Explain the Explain how that would occur. the ERV decrease with exercise assuming that the volume of air was exhaled more than being inhaled at the time. TLC or the total lung capacity does not change with exercise since exercise will not determine the amount of oxygen entering the lung. Inspiratory capacity increased with exercise because of the greater amount of air that could be moved, due to greater tidal volumes. Explain how inhaling increased amounts of CO2 affects pulmonary ventilation. I believe that the changes are caused by the increased need for oxygen and energy in muscles as they have to contract faster during exercise. What is the RQ, and why is it important to assess during rest and exercise? FRC = RV + ERV. How might exercise change expiratory reserve volume? Two factors each have a significant impact on the pCO2. Explain how inhaling decreased amounts of O2 affects pulmonary ventilation. After reviewing the discussion of the respiratory cycle, explain why this change forcefully expels air out the nose and mouth. Air is forced out of the lungs. However whilst breathing, my breathing rate was not normal but it was essential for me to keep the results reliable. Explain why the contraction of the diaphragm and intercostal muscles causes a decrease in intrathoracic pressure. These gases are exchanged with the atmosphere when you breathe.

NRSG 202 Lab: Powerphys 8 and 9 Flashcards | Quizlet high fiber prevents large changes in blood glucose levels. Emphysema causes alveolar dilation and destruction of alveolar walls, which causes an increase in residual volume with air that cannot be exhaled. How does residual volume of the lungs change with age? Residual lung volume increases. What happens to tidal and residual volume during exercise? Minute ventilation? During strenuous exercise, TV plateaus at about 60% of VC but minute ventilation continues to increase. The lungs use it as extra volume for deeper breaths preventing full inspiration.
