What condition involves irritation and inflammation of the bronchi?

• A. Pneumonitis
• B. Bronchitis
• C. Asthma
• D. Chronic Bronchitis

Answer: (B)

The condition that involves irritation and inflammation of the bronchi is bronchitis. This condition is characterized by the swelling of the bronchial tubes, which can lead to symptoms such as coughing, mucus production, wheezing, and difficulty breathing. The inflammation is typically caused by irritants such as tobacco smoke, air pollution, or respiratory infections.

Bronchitis can be classified as acute or chronic. Acute bronchitis usually resolves within a few weeks, often following a viral respiratory infection, while chronic bronchitis is a long-term condition associated with ongoing irritation and damage to the bronchial lining, commonly due to smoking.

Understanding the nature of bronchitis is crucial for distinguishing it from other respiratory conditions, such as asthma or pneumonia, both of which have different underlying mechanisms and symptoms.
