Detailed explanation-1: -In acute exacerbations of asthma, bronchial smooth muscle contraction (bronchoconstriction) occurs quickly to narrow the airways in response to exposure to a variety of stimuli including allergens or irritants.
Detailed explanation-2: -In people with asthma, these muscles often tighten in reaction to certain things. When this happens, the airways become narrower, which blocks the flow of air and makes it harder to breathe. This narrowing of the airways is known as bronchoconstriction.
Detailed explanation-3: -During an asthma episode or attack, the sides of the airways in your lungs swell, and the airways shrink. Less air gets in and out of your lungs, and mucus clogs up the airways even more. Severe asthma attacks can be life-threatening.
Detailed explanation-4: -Bronchial asthma (or asthma) is a lung disease. Your airways get narrow and swollen and are blocked by excess mucus.
