WebJul 31, 2001 · Background Peripheral chemoreceptor hypersensitivity is a feature of abnormal cardiorespiratory reflex control in chronic heart failure (CHF) and may contribute to sympathetic overactivity, attenuated baroreflex sensitivity (BRS), and excessive ventilation during exercise. We studied whether augmented peripheral chemosensitivity carries … WebCentral chemoreceptors: These are located on the ventrolateral surface of medulla oblongata and detect changes in the pH of spinal fluid. …. Peripheral chemoreceptors: These include the aortic body, which detects changes in blood oxygen and carbon dioxide, but not pH, and the carotid body which detects all three.

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. A high concentration of central chemoreceptors is found in the ventral medulla, the brainstem area that receives input from peripheral … See more Peripheral chemoreceptors (of the carotid and aortic bodies) are so named because they are sensory extensions of the peripheral nervous system into blood vessels where they detect changes in chemical … See more • Central chemoreceptors • Chemoreceptors • Control of respiration See more • Nosek, Thomas M.
