Asthma is a condition of sudden paroxysmal, expiratory, wheezing dyspnoea produced by an abnormal response of the respiratory center to stimulus causing hyperactivity of the vagal endings in the broncho-constricting muscles resulting in bronchial spasm; with it, hyperaemia of the mucous membrane followed by excessive bronchial secretion is associated.
