Question

Quizplus · Accepted Answer

During exercise, the demand for ATP increases, leading to increased production of carbon dioxide in the muscles. As a result, there is an increase in carbon dioxide diffusion across the respiratory membrane, which leads to an increase in breathing rate and depth of ventilation to remove the excess carbon dioxide. Blood flow to the lungs also increases to provide adequate oxygen for the working muscles.
