The autonomic nervous system is composed of the sympathetic division and the parasympathetic division. They are complete opposites in every way.
Within the sympathetic nervous system, there is:

the "Fight or Flight" response during moments of stress or fear, or exercise & activity, or impulse to survive
dilation of pupils
dilation of bronchi to let it more oxygen
increased glycogen for glucose to be released in your blood and travel to the muscle/organ tissues
increased heart rate and contraction (beating of heart)
increased sweat secretion
increased renin secretion from kidney, which in turn increases your blood pressure
promotes ejaculation in males

decreased blood flow due to VESSEL CONSTRICTION (blood vessels gets smaller in diameter making it harder for blood to flow through)
decreased peristalsis of organs
decreased digestive secretions, which includes urine, bile, saliva and other digestive juices


 (Parasympathetic division is opposite in every way. "Rest and Digest")
