Definition - Term used to denote bronchial asthma; a condition of the lungs
in which there is widespread narrowing of airways, varying over short periods
of time either spontaneously or as a result of treatment, due in varying degrees
to contraction (spasm) of smooth muscle, edema of the mucosa, and mucus in the
lumen of the bronchi and bronchioles; these changes are caused by the local release
of spasmogens and vaso-active substances in the course of an allergic process.
