One function of the respiratory system is to assist the body in maintaining acid-base balance.

Question

Quizplus · Accepted Answer

The respiratory system helps regulate acid-base balance in the body by controlling the levels of carbon dioxide and oxygen in the blood. Carbon dioxide is acidic, so the body increases respiration (breathing) to eliminate excess carbon dioxide, which helps to decrease acidity and maintain a healthy pH balance. Conversely, if the body becomes too alkaline, the respiratory system decreases respiration to retain carbon dioxide and maintain a more acidic environment.
