Pathophysiology of asthma

 

Asthma is an airway disease that can be classified physiologically as a variable and partially reversible obstruction to air flow, and pathologically the precise study and diagnosis of disease. with overdeveloped mucus glands, airway thickening due to scarring and inflammation, and bronchoconstriction, the narrowing of the airways in the lungs due to the tightening of surrounding smooth muscle. Bronchial inflammation also causes narrowing due to edema and swelling caused by an immune response to allergens.
