Activation of the sympathetic nervous system leads to the release of adrenaline (epinephrine), which binds to beta-2 adrenergic receptors on the smooth muscle cells in the bronchi, causing the muscles to relax and the airways to dilate (bronchodilation). This mechanism helps improve airflow into the lungs.
