Best Answer: Constriction of smooth muscles in the bronchioles is controlled by the parasympathetic nervous system.Antigens, asthma, and inflammatory responses will cause the smooth muscles to contract, narrowing the bronchioles, and reducing air flow, thus reducing oxygen exchange.Such constriction is a protective mechanism for the respiratory system.est Answer: Constriction of smooth muscles in the bronchioles is controlled by the parasympathetic nervous system.
