What is Bronchitis ?
It is the inflammation of the bronchial tube which is caused by bacterial infection, or by smoking. When a person smokes tiny particles of smoke get caught in the living of trachea and bronchial tubes. Extra mucus is produced and the cilia stop beating.
The mucous collects in the bronchial tube producing “smokers a cough”. If the tubes are infected It causes chronic brochettes which may last longer.
