Peripheral chemoreceptors
WebThe peripheral chemoreceptors are directly exposed to arterial blood and are capable of responding to changes in CO 2, O 2, and pH. There are two populations of chemoreceptive cells in the vasculature (see figure 17.4). One population is found in the aortic arch and is referred to as the aortic bodies.
