Review NCLEX Questions Gastrointestinal System related questions and content

It is true to say the following about the motility of the gastrointestinal system:

  • A. It is regulated neurally but not by hormones
  • B. Emptying of the stomach is mainly by segmentation contractions
  • C. Movement of chyme along the small intestine is mainly by the migrating motor complex
  • D. Peristalsis is seen in most parts of the GIT
Correct Answer: D

Rationale: The correct answer is D because peristalsis, a coordinated muscle contraction that propels food along the gastrointestinal tract, is indeed seen in most parts of the GIT. This process helps move food from the esophagus to the stomach, and then throughout the intestines for digestion and absorption. Peristalsis is essential for the proper functioning of the digestive system.

Choice A is incorrect because gastrointestinal motility is regulated by both neural and hormonal factors. Choice B is incorrect as the emptying of the stomach is mainly facilitated by the rhythmic contractions of the stomach muscles, not segmentation contractions. Choice C is incorrect as the movement of chyme along the small intestine is primarily due to segmentation and peristalsis, not the migrating motor complex.
