Define bronchitis??

Bronchitis is a respiratory condition characterized by inflammation of the bronchial tubes, which are the airways that carry air to and from the lungs. This inflammation can cause symptoms such as coughing, chest discomfort, and difficulty breathing. Bronchitis can be acute or chronic, with acute bronchitis typically lasting for a few weeks and chronic bronchitis lasting for several months or longer. It is often caused by viral or bacterial infections, although other factors such as smoking or exposure to irritants can also contribute to the development of bronchitis.
