Question

Quizplus · Accepted Answer

When breathing faster and deeper, more carbon dioxide will be exhaled out of the body, leading to a decrease in the concentration of carbon dioxide in the blood. This concentration gradient will drive more carbon dioxide to diffuse out of the blood in the lungs (from an area of high concentration to an area of low concentration), resulting in choice A being the correct answer.
