Exercise and reactions to exciting stimuli include increased activity in the sympathetic, and decreased activity in the parasympathetic divisions.
<h3>
What is the sympathetic nervous system?</h3>
The autonomic nervous system includes the sympathetic nervous system. It might be referred to as the "automatic" nervous system because it controls many processes that we don't have to think about. This can affect a variety of bodily processes, such as the regulation of our heart rate, blood pressure, digestion, urination, and perspiration. For its role in reacting to risky or stressful conditions, the sympathetic nervous system is best known.
<h3>
What is the parasympathetic nervous system ?</h3>
One of the two functionally separate and perpetually active divisions of the autonomic nervous system is the parasympathetic nervous system (PNS) (ANS). It opposes the sympathetic nervous system, which is the other (SNS). In calm "rest and digest" situations, the parasympathetic nervous system predominates, whereas the sympathetic nervous system activates the "fight or flight" response in stressful circumstances. The major functions of the PNS are to regulate body processes like digestion and urine as well as to store energy for later use.
Hence, Option B is correct. Exercise and reactions to exciting stimuli include increased activity in the sympathetic, and decreased activity in the parasympathetic divisions.
