autonomic nervous system

The autonomic nervous system controls the involuntary action of the body. It mainly controls and integrates the functions of internal organs like heart, blood vessels, glands, smooth muscles and uterus in the body. The autonomic nervous system is subdivided into (i) sympathetic and (ii) parasympathetic system. The organs receive nerves from both sympathetic and parasympathetic nerve fibers. They have antagonistic effects on the organs if one is stimulatory, the other is inhibitory.

Which part of the autonomic nervous system sends more action potentials to effectors to cause responses such as a reduction in heart rate, narrowing of the pupils and an increase in peristalsis of the gut?
