The chemoreceptors that detect decreases in the blood oxygen level are located in the:
A)aortic and carotid bodies
B)medulla
C)pons
D)aortic and cerebral bodies

Question

Quizplus · Accepted Answer

The chemoreceptors that detect decreases in the blood oxygen level are located in the aortic and carotid bodies. These chemoreceptors sense changes in the oxygen, carbon dioxide, and pH levels in the blood, and they play a critical role in regulating breathing to maintain optimal oxygen levels in the body. The medulla and pons are parts of the brainstem that are involved in regulating breathing, but they do not contain the chemoreceptors that detect changes in oxygen levels. The cerebral bodies do not exist, so choice D is incorrect.
