Solution
Carotid bodies and aortic bodies are primarily responsible for detecting oxygen levels in the blood. They are small clusters of chemoreceptors and supporting cells located near the bifurcation of the carotid artery and the aortic arch. They constantly monitor the oxygen, carbon dioxide, and pH levels of the blood. When oxygen levels in the blood drop too low, these bodies stimulate the respiratory center in the brain to increase the rate and depth of breathing, thereby increasing the oxygen levels in the blood. They do not detect stretching of the lungs, oxygen levels in tissues, or the residual volume.
