Antiasthmatic drugs Why asthma makes it hard to breathe Bronchial asthma Air enters the respiratory syste inflammation from the nose and mouth and travels through the bronchial tubes bronchoconstriction airway hyperresponsiveness In a non-asthmatic person In an asthmatic person, the the muscles around the muscles of the bronchial tube bronchial tubes are relaxed tighten and thicken, and the and the tissue thin air passages decor allowing for easy inflamed and mucus airflow filled, making it difficult for air to move Pathophysiology Asthma Asthmatic Lung Inflamed bronchial tube of an asthmatic Normal bronchial tube
Bronchial asthma： inflammation; bronchoconstriction; airway hyperresponsiveness
