What is the function of chemoreceptor reflexes?

What will be an ideal response?


Chemoreceptor reflexes respond to decreasing pH and oxygen levels in the blood and cerebrospinal fluid (CSF) by adjusting cardiovascular and respiratory activity. These reflexes stimulate responses by the cardiovascular centers to increase blood pressure through vasoconstriction and increased cardiac output and stimulate responses by the respiratory centers to increase the respiratory rate, which increases pH and oxygen levels and decreases CO2 levels.
