What bodily function is primarily affected by asthma?

Asthma primarily affects respiration, as it is a chronic inflammatory condition of the airways that leads to difficulty in breathing. In individuals with asthma, the air passages become narrowed due to inflammation and bronchoconstriction, making it hard to get air in and out of the lungs effectively. This can result in symptoms such as wheezing, coughing, chest tightness, and shortness of breath, particularly during physical activity or exposure to triggers like allergens, smoke, or respiratory infections.

The importance of understanding this aspect of asthma is crucial for effective management and treatment. For instance, recognizing the respiratory limitations can help individuals take appropriate measures, such as using rescue inhalers or avoiding known triggers, to minimize asthma attacks and maintain a better quality of life.
