Question

Quizplus · Accepted Answer

Chemoreceptor reflexes respond to changes in the pH of the blood, specifically an increase in carbon dioxide levels which leads to an increase in hydrogen ion concentration and a decrease in pH. This triggers a respiratory response to increase ventilation and remove excess carbon dioxide, restoring pH balance.
