Question

Quizplus · Accepted Answer

The statement C is false because when carbon dioxide levels fall, the body actually reduces the respiratory rate to retain more carbon dioxide, not increase it to bring in more. The respiratory rate adjusts to maintain a balanced level of carbon dioxide, not to unnecessarily expel or intake it when levels are already low.
