WebChemoreceptor function. Introduction. The major oxygen sensors in the human body are peripheral chemoreceptors, also known as interoreceptors-as connected with internal organs, located in the aortic arch and in the body of the common carotid artery. Chemoreceptor function Peripheral chemoreceptors work in concert with central chemoreceptors, which also monitor blood CO 2 but do it in the cerebrospinal fluid surrounding the brain.
