Which of the following does not stimulate peripheral chemoreceptors?
Correct Answer: Hypocapnia
Description: Hypercapnia is a stimulus not hypocapnia.
Low perfusion produces hypoxia and hypercapnia at the level of chemoreceptors; thus stimulating them.
Peripheral arterial chemoreceptors in the carotid and aortic bodies have very high rates of blood flow. These receptors are primarily activated by a reduction in partial pressure of oxygen (PaO2), but they also respond to an increase in the partial pressure of carbon dioxide (PaCO2) and pH.
