Action of each receptor

Question

Quizplus · Accepted Answer

Irritant receptors initiate the cough reflex by responding to irritating particles or gases in the airways. They are located in the respiratory tract, particularly in bronchi and bronchioles.

Answer: B
 Stretch receptors respond to changes in lung volume and help regulate breathing rate and depth. They are located in the airway smooth muscle and in the lung parenchyma.

Answer: C
 J receptors (Juxtapulmonary Capillary Receptors) are activated by pulmonary capillary congestion and cause rapid, shallow breathing and a sense of dyspnea. They are located in the pulmonary interstitium, between the alveolar epithelium and capillaries.

Answer: D
 Peripheral chemoreceptors detect changes in arterial oxygen, carbon dioxide, and pH levels, and respond by initiating reflexes that increase breathing rate and depth. They are located in the carotid bodies and aortic bodies, near the bifurcation of the respective arteries.

Answer: E
 Central chemoreceptors detect changes in brain extracellular fluid pH and respond by altering breathing rate and depth. They are located in the medulla oblongata, near the respiratory center.
