Explanation:
- Asthma is characterized by:
- Inflammation of the small airways: This is a key feature of asthma, where inflammation of the bronchi and bronchioles leads to narrowing of the airways and difficulty breathing.
- Reversible bronchospasm: In asthma, the airway narrowing caused by bronchospasm (muscle tightening around the airways) is typically reversible with treatment (such as bronchodilators).
- Mucus production: Asthma often involves increased mucus production in the airways, which can contribute to coughing and difficulty breathing.
- However, productive cough for three months per year is not characteristic of asthma. This is more commonly associated with chronic bronchitis, which is a type of chronic obstructive pulmonary disease (COPD). Chronic bronchitis is characterized by a persistent productive cough for at least three months per year for two consecutive years.
Thus, the statement “Productive cough for three months per year” is not characteristic of asthma.
