Hey there,

1) Parasympathetic nervous system :-

It is also written as PNS. It is Involuntary in nature. It serves to slow down the rate of heart activities , it works in increasing glandular activities etc.

2) Sympathetic nervous system :-

It is also written as SNS. It is Involuntary in nature. It serves to increase heart rate , it slows down glandular activities , it makes pupil large, etc.

Sympathetic nervous system + Parasympathetic nervous system = Autonomous nervous system

Thanks!
