Keeping this in consideration, what do J receptors do?
Juxtacapillary receptors. Although their functional role is unclear, J-receptors respond to events such as pulmonary edema, pulmonary emboli, pneumonia, congestive heart failure and barotrauma, which cause a decrease in oxygenation and thus lead to an increase in respiration.
Also, what receptors are in the lungs? Pulmonary stretch receptors. Pulmonary stretch receptors are mechanoreceptors found in the lungs. When the lung expands, the receptors initiate the Hering-Breuer reflex, which reduces the respiratory rate. Increased firing from the stretch receptors also increases production of pulmonary surfactant.
Keeping this in consideration, what is the purpose of the Hering Breuer reflex?
The Hering–Breuer inflation reflex, named for Josef Breuer and Ewald Hering, is a reflex triggered to prevent the over-inflation of the lung. Pulmonary stretch receptors present on the wall of bronchi and bronchioles of the airways respond to excessive stretching of the lung during large inspirations.
What are irritant receptors?
Pulmonary Irritant Receptors are sensors present within the respiratory epithelium which can sense and respond to a variety of chemical irritants. Afferent signals from these sensory cells may initiate coughing in response to a variety of inhaled irritants and might induce bronchoconstriction in those with asthma.
