Specialized _______ in the medulla and in the walls of the aorta and carotid arteries are sensitive to changes in arterial carbon dioxide concentration.

Question

Quizplus · Accepted Answer

Chemoreceptors in the medulla and carotid arteries are sensitive to changes in arterial carbon dioxide concentration, known as hypercapnia. This triggers an increase in respiratory rate to remove excess carbon dioxide and restore normal levels. Mechanoreceptors would respond to changes in pressure, proprioceptors to changes in body position and movement, and thermoreceptors to changes in temperature.
