Peripheral chemoreceptors act most importantly
to detect variation of the oxygen in the arterial blood, in addition to
detecting arterial carbon dioxide and pH.
These nodes, called the aortic body and carotid body, are located on the arch of the aorta and on the common
carotid artery, respectively.
A continual signal is sent, via cranial nerves IX and X, from the peripheral
With a decrease in arterial oxygen tension, the signal
intensifies, calling for an increase in respiration.
