Quizplus · Accepted Answer

The respiratory center is directly sensitive to the levels of hydrogen ions (H⁺)in the blood.However,when carbon dioxide (CO₂)enters the blood,it reacts with water and releases hydrogen ions.In this way,CO₂ participates in regulating the breathing rate.When hydrogen ions rise in the blood and the pH decreases,the respiratory center increases the rate and depth of breathing.
