Explanation:

The autonomic nervous system controls the organs and glands located inside our body. The sympathetic and parasympathetic nervous systems are the two divisions of the autonomic nervous system.

The sympathetic nervous system prepares our body to meet an emergent situation by dilating pupils, increasing heart rate and blood pressure and level of adrenaline into his bloodstream.

When threat is resolved the parasympathetic nervous system gets activated and it helps our body to return to the normal function by reverting the processes carried out by the sympathetic nervous system during an emergency.
