Q. Respiratory peripheral chemoreceptors: (Solved)
1. carotid bodies respond to PO2, PCO2, and pH
2. peripheral chemoreceptor response to arterial PCO2 is more important than central chemoreceptor response
3. aortic bodies are located within the aortic valve ring
4. drop in PO2 < 100mmHg causes increase in firing rate
5. carotid bodies respond to venous PO2
- d. drop in PO2 < 100mmHg causes increase in firing rate
