Airways in bronchitis. Illustration showing the airways (bronchi) of the lungs in bronchitis (left) and in a healthy person (right). Bronchitis is a disease where the mucous membranes of the bronchi (airways in the lungs) become inflamed and clogged with mucus. There are two types: acute and chronic. The former is usually the result of a cold or viral infection, and the latter is often the result of smoking tobacco or long-term exposure to air pollution. | |
