Bronchitis And Its Common Characteristics Bronchitis is an inflammation of the bronchial tubes, or bronchi (the air passages that extend from the windpipe into the lungs). The inflammation may be caused by a virus, bacteria, smoking or the inhalation of chemical pollutants or dust. The bronchi are large delicate tubes in the lungs that are attached to the trachea and carry air to smaller tubes in the lungs, a better way of explaining it is: the way of the human respiratory system. When the cells of bronchial-lining tissue are irritated to a certain point, the little hairs in the nostrils called the cilia do not function. Their function is to keep out foreign invaders from entering through the nostrils by trapping them, if the invaders enter, the air passages can get infected and clogged with the debris coming from that foreign invader. From this, mucus slowly develops. Since the air passages protect themselves with the nasal passage’s mucus membrane, the cilia can’t protect the air passage ways. So this causes the cough of bronchitis. Acute bronchitis can come from a severe cold and/or flu. Acute bronchitis can begin without having any kind of infection, but it usually lasts about 10 days. The most effective way to deal with acute bronchitis is bronchitis, air, mucus, acute, smoking, way, sacs, chronic, tubes, respiratory, bronchial, alveoli, about, year, trachea, through, results, pneumonia, plug, passages, one, lungs, cause, bronchi, being, ways, walls, very, throat, thin, thickened, system, surface, smoker, smoke
