Detailed explanation-1: -Asthma is a condition in which your airways narrow and swell and may produce extra mucus. This can make breathing difficult and trigger coughing, a whistling sound (wheezing) when you breathe out and shortness of breath. For some people, asthma is a minor nuisance.

Detailed explanation-2: -Asthma is caused by inflammation of the small tubes, called bronchi, which carry air in and out of the lungs. If you have asthma, the bronchi will be inflamed and more sensitive than normal.

Detailed explanation-3: -Inflammation of the airways. Asthma is based on an aberrant immune response to non‐pathogenic stimuli in the airways leading to a chronic inflammatory response relevant to the pathogenesis of the disease. The inflammation affects all compartments of the airways including the upper respiratory tract and the nose.
