Bronchial tubes are airways that deliver air into the lungs. With chronic bronchitis, breathing in tobacco smoke and other irritants over time can make the airways inflamed. The airways make more mucus than normal. This reduces air flow and makes you cough. Over many years, damage to the lungs can grow worse and become a lifelong condition.
