Control of respiration is based on input from mechanoreceptors that monitor lung inflation and chemoreceptors that monitor blood O2, CO2, and pH.
- Chemoreceptor feedback is one method used to regulate breathing.
- The brain's central chemoreceptors, which react to changes in the partial pressure of carbon dioxide in their immediate environment, and arterial chemoreceptors, which monitor and react to changes in the partial pressure of oxygen and carbon dioxide in the arterial blood, are two different types of respiratory chemoreceptors.
- Ventilation levels act as though they were controlled to keep the arterial blood adequately oxygenated and to maintain a consistent level of carbon dioxide partial pressure.
- Both the rate and depth of breathing rise when chemoreceptor activity is increased due to hypoxia or an increase in carbon dioxide partial pressure, which returns oxygen and carbon dioxide partial pressures to their normal levels.
- On the other hand, excessive ventilation lowers the partial pressure of carbon dioxide, which reduces the activity of chemoreceptors and decreases ventilation.
