Question

Quizplus · Accepted Answer

The chemoreceptors in the carotid and aortic bodies detect changes in the levels of PCO₂, PO₂, and pH in the blood, and relay this information to the brain to regulate breathing. Therefore, blocking afferent action potentials from these chemoreceptors would interfere with the brain's ability to regulate breathing in response to changes in any of these variables.
