WebPeripheral chemoreceptors (carotid and aortic bodies) and central chemoreceptors (medullary neurons) primarily function to regulate respiratory activity. This is an … WebJul 31, 2024 · The central and peripheral chemoreceptors monitor the arterial blood gases-O 2, CO 2, and pH. A chemoreceptor is a receptor that responds to a change in the chemical composition of the blood or other fluid around it. The minute respiratory volume is proportional to the metabolic rate.
WebOct 11, 2024 · Within the central nervous system, central chemoreceptors are located just below the ventrolateral surface of the medulla. These chemoreceptors detect changes in the P co 2 /pH of brainstem interstitial fluid and modulate ventilation. Peripheral structures also provide input to the integrator and control ventilatory drive. WebThe peripheral chemoreceptor came to the rescue. Its sensitivity to P(O2) is increased which continues to drive ventilation further during acclimatization at high altitude even when pH is alkaline. This link of CO2 through the O2 chemoreceptor is described in Section 4 which led to hypoxia-inducible factor (HIF-1).
WebPeripheral chemoreceptors ( carotid and aortic bodies) and central chemoreceptors (medullary neurons) primarily function to regulate respiratory activity. This is an important mechanism for maintaining arterial blood PO 2, PCO 2, and pH within appropriate physiological ranges.
