Asthma is characterized by which of the following?

Asthma is indeed characterized by an inflamed airway, which leads to excess mucus production. This condition arises from chronic inflammation of the bronchial tubes, making them sensitive to various triggers, such as allergens, smoke, and exercise. When an individual with asthma encounters these triggers, the airways constrict, swell, and produce more mucus, which contributes to symptoms like coughing, wheezing, and shortness of breath. The inflammation and mucus production narrow the airways, making it difficult for air to flow in and out of the lungs, which is the hallmark of an asthma attack. Understanding this mechanism is crucial for managing and treating asthma effectively.
