The location of the central chemoreceptor is:
The cerebral cortex
The brain stem
The aorta
The cerebellum
The Correct Answer is B
A. The cerebral cortex is involved in higher brain functions like thinking and voluntary control of breathing but does not contain central chemoreceptors.
B. Central chemoreceptors are located in the medulla oblongata, a part of the brain stem. They detect changes in the pH of cerebrospinal fluid, which reflects CO₂ levels in the blood, and help regulate breathing accordingly.
C. The aorta contains peripheral chemoreceptors, not central ones. These aortic bodies monitor blood oxygen, carbon dioxide, and pH, but they are outside the central nervous system.
D. The cerebellum coordinates motor control and balance and does not play a role in chemoreception.

C. Arterioles are small blood vessels that are part of the circulatory system, not the respiratory system.
D. The alveoli are the small air sacs at the end of the bronchioles where gas exchange occurs, but they are not the smallest subdivision of the bronchial tree—this is the bronchiole itself.
