What role of chemo receptors play in breathing?

Chemoreceptors play a crucial role in regulating breathing by detecting changes in the levels of carbon dioxide (CO2), oxygen (O2), and pH in the blood. Central chemoreceptors, located in the brainstem, primarily respond to rising CO2 levels, which signal the body to increase the rate and depth of breathing. Peripheral chemoreceptors, found in the carotid and aortic bodies, monitor O2 levels and also contribute to the respiratory response. Together, these chemoreceptors help maintain homeostasis by ensuring adequate oxygen supply and efficient removal of carbon dioxide.
