Movement of food in the small intestine. Thus, option "D" is correct.
<h3>What is the autonomous nervous system? </h3>
ANS is divided in two opposite systems: sympathetic and parasympathetic:
Parasympathetic nervous system: characterized by the tag "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).
Sympathetic nervous system: characterized by the tag "fight or flight" it increases the heart rate, blood pressure, and breath. It decreases gastrointestinal motricity, letting the organism focus on its environment (this happen when we are in danger).
Thus, option "D" is correct.
