In response to a trigger, two physiological processes occur called bronchoconstriction and inflammation. During bronchoconstriction, the smooth muscles along the airways to tighten, narrowing the passage and making it more difficult for air to flow into the lungs. The airways could also become inflamed and swollen which further reduces the passage of air in the lungs,
