Question

Quizplus · Accepted Answer

Medullary breathing centers, specifically the dorsal respiratory group (DRG) and ventral respiratory group (VRG), directly sense changes in blood pH and CO2 concentration through chemoreceptors. This information is then used to adjust the rate and depth of breathing to maintain homeostasis. Blood O2 concentration, while important, is primarily sensed and responded to by peripheral chemoreceptors located in the carotid and aortic bodies.
