Explanation: Ref: Textbook of pathology (Harsh Mohan) 6th edition, page No.483 BRONCHIAL ASTHMA Asthma is a disease of airways that is characterised by increased responsiveness of the tracheobronchial tree to a variety of stimuli resulting in widespread spasmodic narrowing of the air passages which may be relieved spontaneously or by therapy.
