Meaning and Definition

An automatic reflex action triggered by chemical stimuli, especially in the context of respiratory or cardiovascular regulation.

A specific physiological reflex response initiated by chemical changes detected by receptors (chemoreceptors), commonly involved in controlling breathing rate, heart rate, or blood pressure.

  • Mispronouncing with stress on 're' (e.g., chemoreFLEX) instead of on the first syllable.

FAQ

Frequently Asked Questions

No, it is an entirely unconscious, automatic reflex mediated by the autonomic nervous system.

The increase in breathing rate (ventilation) triggered by elevated carbon dioxide levels in the blood.

Central chemoreflexes are located in the brainstem and respond primarily to CO2/pH changes in cerebrospinal fluid. Peripheral chemoreflexes are located in arteries (carotid and aortic bodies) and respond to low O2, high CO2, and low blood pH.

Almost never. It is a specialized term used among healthcare professionals and researchers, not in patient communication.
