bronchoconstriction [brong″ko-kon-strik´shun] narrowing of a bronchus as a result of smooth muscle contraction, as in asthma.bron·cho·con·stric·tion (brong'kō-kon-strik'shŭn), Reduction in the caliber of a bronchus or bronchi, usually referring to a dynamic process as in asthma and emphysema, rather than a fixed constriction (the latter is a bronchial stenosis). Compare: bronchospasm. bronchoconstriction The narrowing of a bronchus due to the contraction of the surrounding smooth muscle, which may be caused by either histaminic-H1/2 or muscarinic (M1/2/3) receptors.bronchoconstriction Narrowing of a bronchus, bronchostenosisbron·cho·con·stric·tion (brong'kō-kŏn-strik'shŭn) Constriction of the bronchi. bronchoconstriction Contraction of the circular muscles in the walls of the bronchi, so narrowing the bore of the tubes and restricting air entry.
