Describe how the central chemoreceptors act to regulateventilation. Be sure to describe the integrating centers andsensors involved, their locations, and explain their roles indetermining ventilation rate. Be sure to include any chemicalequations (and enzymes!) that are necessary to explain ventilationregulation and explain how the mechanisms work. Then explain howthe system responds when arterial blood pH is elevated, and explainhow the response corrects arterial CO2. Explain how thesystem responds when arterial blood pH is decreased, and explainhow the response corrects arterial CO2.
Describe how the peripheral chemoreceptors act to regulateventilation. Be sure to name the sensors involved, their locations,and explain their roles. Be sure to include the molecules sensed,and any chemical equations (and enzymes!) that are necessary toexplain their roles. Then explain how and when the system acts toincrease ventilation. Explain how and when the system acts todecrease ventilation.
