What physiological changes occur during an asthma attack?

Question

Quizplus · Accepted Answer

During an asthma attack, the bronchioles (small airways) in the lungs become narrowed due to inflammation, thickening of the airway walls, and increased mucus production. This makes it difficult for air to flow in and out of the lungs, leading to shortness of breath, wheezing, and coughing. There is also some degree of airway hyperresponsiveness or twitchiness, which means that even minimal exposure to irritants or allergens can trigger an attack. Pleural lubrication, which is the fluid that helps the lungs move smoothly against the chest wall, is not directly affected by asthma.
