Bronchoconstriction is a constriction of the airways in the lungs due to the contraction of the surrounding muscles. It is characterized by coughing, wheezing and shortness of breath. It can be caused by spasms of the muscles surrounding the lung, inflammation of the bronchii, or excessive production of mucous. Any of these conditions will cause the release of acetylcholine which triggers the muscle contraction.
