Chemoreceptor
= Chemoreceptor
A <chemoreceptor> is a sensory cell or receptor system responding to chemical composition. In respiratory regulation, carbon-dioxide-related chemical signals contribute to feedback controlling <pulmonary ventilation>[ventilation]. Blood transport and neural response introduce delays, so a lumped <pulmonary ventilation>[ventilation] model may respond to past rather than present <carbon dioxide>[carbon-dioxide] <partial pressure>[partial pressure].
