We just learned about the Sympathetic Nervous System.
Another part of the Autonomic Nervous System is the Parasympathetic Nervous System, sometimes just called the PSNS.
Remember the Sympathetic Nervous System gives us the "fight or flight" feelings.
The PSNS gives us what we call the "rest-and-digest" feelings.
These are more for when you are sitting at rest, eating or just relaxing.
