Explanation:

Parasympathetic nervous system and the sympathetic nervous system are two of the 3 domains of the autonomic nervous system.

During the resting and the relaxing stage,<u> parasympathetic system</u> (also called as rest or digest system) is activated which is associated with the conservation of the energy by :

1) Slowing the heart rate

2) Increasing the intestinal activity ( the reason why  Jane is relaxing comfortably as her food digests )

3) Relaxation of the sphincter muscles of the GIT.

While during the fight , flight or fright stage , the <u>sympathetic nervous system</u> is activated which is associated with the body alertness by :

1) Increasing the heart rate

2) Inhibition of secretion of GIT enzymes ( the reason why digestion of JANE is inhibited )

3) Relaxation of the walls and the contraction of the sphincters of the GIT smooth muscle.
