Question is short but answer is bit long. Parasympathetic system is meant for to to maintain the homeostasis and body building. Sympathetic system is meant to give you ' Fight or flight response. So you have pupils constricted in parasympathetic and dilated in sympathetic response. You need not see towards the world during first and need to look at the world carefully in danger. Secretions of gastrointestinal system are increased, peristalsis is increased, spinctures are opened up during stimulation of the parasympathetic system. This helps in digestion and body building. Vise verse is true with sympathetic system. During stimulation of the sympathetic system your cardiovascular system is on the toes, to supply more blood to muscles. So the heart rate is increased, stroke volume is increased ans as a result you have great increase in cardiac output. So cardiac output may go to 25 litres / minute from 5 litres / minutes. Blood vessels to muscles are dilated, so that almost 20 litres blood goes to muscles. Net increase from 0.5 litres to 20 litres / minute. In respiratory system you have bronchial system dilated to provide more oxygen to lungs in sympathetic stimulation, the bronchial secretions are less in amount and respiratory rate increases to high level. Vise verse is true with parasympathetic system, when you are resting and need less of the oxygen. In parasympathetic system you have contraction of urinary bladder and relaxation of the spincture to void the urine. During stress you have no time for urination and reverse is true. Erection of penis is managed by parasympathetic system and ejaculation is done by sympathetic system.

The effects of the sympathetic nervous system are essentially opposite of which nervous system?
The effects of the sympathetic nervous system are essential opposite those of the parasympathetic nervous system. The sympathetic nervous system accelerates functions such as heart rate and breathing and the parasympathetic slows these bodily processes down. The sympathetic also inhibits digestion, whereas the parasympathetic stimulates digestion. The sympathetic nervous system produces "fight-or-flight" reactions, while the parasympathetic functions under relaxed conditions.
