The Autonomic Nervous System Can Be Challenging To Understand Because It Is Connected To Virtually Every

The Autonomic Nervous System can be challenging to understand because it is connected to virtually every body function in opposite ways
We are going to explore the physiology of the ANS in this discussion by looking at specific examples of how it works
  Initial post:  For your first discussion post, describe how the parasympathetic nervous system influences one function in your body
For example, the parasympathetic nervous system causes decreased blood pressure
If you chose this body function, you would describe the physiology behind the decreased blood pressure
How does it happen? What occurs in the heart/blood vessels? Which scenarios or external factors would cause the parasympathetic nervous system to activate this response?
