This part of our nervous system helps bring our bodies back to a calm state after arousal. It's like hitting the 'restore' button on your computer after you've finished running heavy applications.
Digestive System: This system breaks down food into nutrients that can be used by the body. Think of it as your computer processing new data (food) into usable information (nutrients).
This controls involuntary actions such as heartbeat, digestion, etc., without conscious thought. It's like your computer’s operating system managing all its processes automatically.
