In asthma the bronchial tubes are inflamed that causes narrowing of the airways. When the airways or bronchial tubes are narrowed it prevents the free flow of air in the bronchial tubes. The smooth muscles layers surrounding the bronchial tubes are tightened and compress the small bronchioles which causes narrowing of air passages. The narrowing of air passages obstructs the smooth air flow by which the person feels of tightness in chest, shortness of breath and difficulties in breathing. Here one thing need to be discussed why some peoples are getting asthmatic attack but not all. It is because the bronchial tubes of an asthmatic person is overly sensitive to many substances ; when exposed to those substances, the bronchial tubes get narrows and create problem for free flow of air in it. It is because some people are very sensitive to some substances and when get expose to them start reacting adversely and the mucous membrane of the inner layer of bronchial tube get inflamed and initiate the asthmatic condition.
Coughing – in a healthy person coughing is a protecting step of the respiratory system not to allow entry of any outside substances into the lungs by clearing it out from the air passages. In asthmatic condition the air ways are swollen that the body thinks of any outer substance stick on it so try to expel out and produce cough. The more he coughs the more bronchial spasm occurs and the discomfort is felt more.
