An asthma attack

Question

An asthma attack

Quizplus · Accepted Answer

An asthma attack is characterized by abnormal increases in bronchoconstriction, which results in the narrowing of the airways and making it difficult to breathe. This may be caused by inflammation, irritation, or other triggers, such as allergens, pollution, or exercise. There may also be an immune or allergic component involved, but this is not always the case. The attack may be worsened during or after strenuous exercise, and there is no increase in bronchodilation during an attack. Lastly, asthma attacks can occur in any location, regardless of cell division or gene expression.
