The sympathetic nervous system is the part of the autonomic nervous system which prepares the body for fight-or-flight actions.
In this regard, it causes a release of the hormone adrenaline (epinephrine), increases heart-rate and the force of contraction of the heart (which sends more oxygen to the muscles of the body, for running or fighting), widens bronchial passages (so more oxygen can be inhaled quickly), increases blood pressure, releases glucose from the liver (fuel for running or fighting), decreases blood flow to the intestines (so more blood goes to the muscles), speeds up blood clotting function (damage control), increases perspiration (to help cool the body during exertion), and dilates the pupils of the eyes (to better focus on danger).
