Question

Quizplus · Accepted Answer

Chemoreceptors are responsible for detecting chemical changes in the blood, including changes in oxygen and carbon dioxide levels. When the amount of oxygen in the blood decreases during exercise, chemoreceptors send signals to the medulla to increase the rate of breathing to bring in more oxygen and eliminate excess carbon dioxide.
