A female patient, having visited the factory premises with lots of dust in the air for the first time, has got cough and burning pain in the throat. What respiratory receptors, when irritated, cause this kind of reaction?

Answer options

1. Juxtacapillary (J) receptors
2. Proprioceptors of respiratory muscles
3. Irritant receptors
4. Thermoreceptors
5. Stretch receptors of lungs

Explanation

Pulmonary Irritant Receptors are sensors present within the respiratory epithelium that can sense and respond to a variety of chemical irritants. These sensory cells may initiate coughing in response to a variety of inhaled irritants and might induce bronchoconstriction.
