Which of the following are chemoreceptors? hair cells in the cochlea receptors in the aortic and carotid bodies baroreceptors in
Mrac [35]

Answer:

The receptors in the aortic and carotid bodies are chemoreceptors.

Explanation:

Chemoreceptors are specialized cells that are responsible for detecting and converting chemical signals into biological signals, to relay that information to the brain, where they will finally be interpreted. Among them we find the peripheral chemoreceptors, which are the aortic bodies, located along the wall of the aortic arch and innervated by the vagus nerve, and the carotid bodies, located in the neck. . Carotid bodies are stimulated by variations in the concentration of oxygen and carbon dioxide in the blood, as well as variations in blood pH. When the pH decreases the CO2 increases and the oxygen decreases, they activate the chemoreceptors to increase breathing.
