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.

Somehow similar to bronchitis, it is acute respiratory distress.

For a smoker; the inflammation of the bronchi and bronchial tubes
