Which of the following structures does not send input to the dorsal respiratory group?

A) Central chemoreceptors
B) Stretch receptors
C) Peripheral chemoreceptors
D) Irritant receptors
E) All of these structures send input to the dorsal respiratory group.

Dorsal Respiratory Group

A cluster of neurons located in the medulla oblongata that plays a crucial role in regulating the rhythm of breathing.

Central Chemoreceptors

Brainstem neurons that detect changes in the pH of cerebrospinal fluid and help regulate ventilation rate.

Peripheral Chemoreceptors

Sensory receptors located in the carotid bodies and aortic bodies that detect changes in the chemical composition of the blood, primarily oxygen, carbon dioxide, and pH levels.
