Specialized receptors called _______ in the medulla and in the walls of the aorta and carotid arteries are sensitive to changes in arterial carbon dioxide concentration.
A) chemoreceptors
B) baroreceptors
C) nociceptors
D) carboreceptors

Question

Quizplus · Accepted Answer

Chemoreceptors are specialized receptors that are sensitive to changes in the chemical composition of blood and are located in the medulla and walls of the aorta and carotid arteries. They respond primarily to changes in arterial carbon dioxide (CO2) concentration, which is an important regulator of breathing. Baroreceptors, on the other hand, are specialized receptors that are sensitive to changes in blood pressure and are located in the walls of certain blood vessels. Nociceptors are specialized receptors that respond to painful stimuli, while carboreceptors are not a known type of receptor.
