Question

Quizplus · Accepted Answer

Anaphylaxis is not a key component of a typical asthma attack. Asthma attacks are usually triggered by allergens, irritants or physical exercise, causing inflammation of airways, spasm of surrounding muscles and secretion of extra mucus. Anaphylaxis is a severe allergic reaction that can occur as a result of exposure to certain allergens or medications, but it is not a characteristic feature of asthma attacks.
