Explanation:
- Both sympathetic and parasympathetic nervous system are the types of the autonomic nervous system.
- The sympathetic system is activated when the person faces the stress condition while the parasympathetic system is activated when the person is in relaxed conditions.
- The sympathetic system increases heartbeat and constricts the blood vessels whereas the parasympathetic system dilates the blood vessels that increase the blood flow in the vessel.
