What is inflammation in the airway commonly associated with?

Inflammation in the airway is primarily characterized by the swelling of the lining of the airway. This swelling occurs as a response to irritants, allergens, or infections, leading to increased mucus production and narrowing of the air passages. Consequently, this physiological change can cause difficulty in breathing, wheezing, and other respiratory symptoms.

Understanding this mechanism is crucial, especially in relation to conditions such as asthma and chronic bronchitis, where airway inflammation plays a significant role. By recognizing that swelling of the airway lining is central to these conditions, individuals can better understand the importance of maintaining open and clear airways for effective respiration.
