The cough reflex occurs when stimulation of cough receptors in the respiratory tract by dust or other foreign particles produces a cough, which causes rapidly moving air which usually remove the foreign material before it reaches the lungs.
A cough is a sudden expulsion of air through the large breathing passages which can help clear them of fluids, irritants, foreign particles and microbes.As a protective reflex, coughing can be repetitive with the cough reflex following three phases: an inhalation, a forced exhalation against a closed glottis, and a violent release of air from the lungs following opening of the glottis, usually ...

To determine if a person has chronic cough, a healthcare provider may ask questions about medical history, perform a physical exam, and run tests, such as chest x-rays, throat swabs, blood samples ...
The gag reflex involves a brisk and brief elevation of the soft palate and bilateral contraction of pharyngeal muscles evoked by touching the posterior pharyngeal wall.

Besides a cough, signs of an upper respiratory infection include fever, a hoarse voice, fatigue or lack of energy, red eyes, a runny nose, a sore throat and swollen lymph nodes (aka swelling on ...
The other clearance mechanism is provided by the cough reflex. [2] Mucociliary clearance has a major role in pulmonary hygiene . MCC effectiveness relies on the correct properties of the airway surface liquid produced, both of the periciliary sol layer and the overlying mucus gel layer , and of the number and quality of the cilia present in the ...
