Cough is caused by foreign bodies, irritant gases, secretions in the respiratory tract and so on, when they stimulate the receptors in the respiratory tract mucosa, impulses pass through the afferent nerve fibers to the cough center of the medulla oblongata, causing cough.
The action of coughing is short and deep inspiration, the glottis is closed, and the respiratory muscles, intercostals and diaphragmatic muscles contract rapidly and violently, so that the high-pressure gas in the lungs is ejected, which is called cough. With the rapid flow of air, foreign bodies or secretions in the respiratory tract are discharged from the body.
