In the AORTA and in the CAROTID ARTERY
The function of the chemoreceptors in regulating breathing is that they respond to low levels of oxyhemeglobin.

The receptors that are likely to detect changes in carbon dioxide and oxygen concentration in the blood are chemoreceptors located in the aorta and carotid arteries. These chemoreceptors detect changes in the pH of the blood and send signals to the brain to regulate breathing heart rate and other bodily functions. The receptors are sensitive to the following: Carbon dioxide concentration Oxygen concentration pH of the bloodThe chemoreceptors are located in the walls of the aorta and carotid arteries and are sensitive to the changes in carbon dioxide and oxygen concentrations. When the concentrations of these two gases change the chemoreceptors send signals to the brain which then responds with appropriate adjustments in breathing rate and heart rate.

Central chemoreceptors of the central nervous system are located on the ventrolateral medullary surface.

The medulla oblongata, which is the most inferior part of the brainstem, contains the nuclei that regulate our rate and depth of breathing.
