Question
You go for a morning run. Your respiratory rate will increase because*1 pointyou are consciously controlling it.your cells are building up more carbon dioxide.the pH of your blood is rising.both B and C are correct.
Solution
The respiratory rate increases during a morning run primarily because your cells are building up more carbon dioxide. When you exercise, your muscles work harder and produce more carbon dioxide as a waste product. This increase in carbon dioxide levels signals your brain to increase your respiratory rate to expel the excess carbon dioxide from your body and take in more oxygen, which your muscles need for energy. Therefore, the correct answer is "your cells are building up more carbon dioxide."
