GENERAL KNOWLEDGE

Detailed explanation-1: -Bronchitis is a condition that develops when the airways in the lungs, called bronchial tubes, become inflamed and cause coughing, often with mucus production. Bronchitis can be acute (short-term) or chronic (long-term).

Detailed explanation-2: -Bronchitis is an inflammation of the lining of your bronchial tubes, which carry air to and from your lungs. People who have bronchitis often cough up thickened mucus, which can be discolored. Bronchitis may be either acute or chronic.

Detailed explanation-3: -Bronchitis (chest cold) is not an upper respiratory tract infection. Rather, it affects the air-transporting tubes of the lungs (bronchioles), which are a part of the lower respiratory tract.
