The role of the parasympathetic nervous system is a) prepare the body for flight-or-flight response b) establish homeostasis after the fight-or-flight response c) prompt the body to use its resources in responding to an emergency d) prepare the body to cope with stress e) communicate between the afferent and efferent neurons

The role of the parasympathetic nervous system is to establish homeostasis after the fight-or-flight response.

Option B

The "parasympathetic nervous system (PSNS)" is part of the nervous system that transfers signals between the different parts of the body through nerves. The opposite of the PSNS is the sympathetic nervous system (SNS). For example when an animal is deciding either to fight or flee.

At that moment the heart rate and the blood pressure of that animal increases and the SNS is in charge of this particular behavior that is exhibited. On the other hand, the PSNS is in control of the bodily functions that occur when an animal is at rest. It helps calm the animal down i,e., decrease its heart rate and lower its blood pressure.
