chemoreceptor reflex

physiology

Quick Summary

The chemoreceptor reflex is a physiological process that helps regulate breathing by sensing changes in blood chemistry. Specialized sensors called chemoreceptors, located in the brainstem and major arteries, monitor levels of oxygen and carbon dioxide.

When oxygen levels drop or carbon dioxide levels rise, these chemoreceptors signal the brain's respiratory centers. This triggers an increase in the rate and depth of breathing to restore normal blood gas levels. This reflex is crucial for maintaining adequate oxygen supply and removing excess carbon dioxide from the body. The process is a vital part of how the body adjusts to varying metabolic demands and environmental conditions.12
