</span>Parasympathetic nervous system: caracterized by the tag "<span>rest and digest" it decreases the heart rate, blood pressure, and breath. It increases the gastrointestinal motricity, letting the organism resting (this happen after a meal).
</span>Sympathetic nervous system: caracterized by the tag "fight or flight" it increases the heart rate, blood pressure, and breath. It decreases the gastrointestinal motricity, letting the organism focus on its environment (this happen when we are in danger).
