Which of the following can stimulate the J-receptors?
I. Alveolar inflammation
II. Pulmonary capillary edema
III. Pulmonary emboli
IV. Hypercapnia

Question

Quizplus · Accepted Answer

J-receptors, also known as pulmonary J receptors or juxtapulmonary-capillary receptors, are located in the alveolar walls close to the capillaries in the lungs. They can be stimulated by factors that affect the interstitial space of the lung, such as alveolar inflammation, pulmonary capillary edema, and pulmonary emboli. Hypercapnia, which is an increase in the carbon dioxide (CO2) level in the blood, does not directly stimulate J-receptors but affects chemoreceptors that regulate breathing.
