A decrease in arterial $P _ { o _ { 2 } }$ stimulates increased ventilation by causing increased firing of action potentials in the afferent neurons from the carotid and aortic body chemoreceptors.

Question

Quizplus · Accepted Answer

This is a true statement. The carotid and aortic body chemoreceptors are sensitive to changes in arterial $P _ { o _ { 2 } }$, and when there is a decrease in $P _ { o _ { 2 } }$, they signal the respiratory center in the brainstem to increase ventilation. This is known as the hypoxic drive.
