Peristalsis and segmentation motion are two types of movement of muscles that occurs on the channel digestion. Both serve for the movement of the nan through channel digestion.

The difference main between the peristalsis and segmentation motion is that the peristalsis motion is the movement of one direction in the direction of the caudal, while segmentation motion function for movement in both directions, so that allows great mixing.

Furthermore, peristalsis occurs by contraction of circular muscles while segmentation occurs due to rhythmic contractions of longitudinal muscles. Also, peristaltic mainly occur in the esophagus, while segmentation especially occurs in the intestine smooth and great.

Definition of Peristalsis Motion

Peristalsis motion is the movement of muscles symmetrical radial function for the dissemination of the material. Generally, it is more often the case in the esophagus tract digestion, push food from the mouth to the stomach. Contraction of the muscles around the walls of the esophagus to function for the peristalsis motion. Moreover, it moves in one direction.

Furthermore, it contraction primer happened the first time with the entry of the bolus into the esophagus after swallowing. This contraction lasts about 8-9 seconds. However, if the bolus stalled or moving slowly, peristalsis motion secondary occurs in approximately bolus with stimulation of the reflex locally. Therefore, things that force bolus down.

Definition of Segmentation Contractions

Segmentary motion is a type of local contraction of circular muscles in the digestive tract. In general, this is especially true in the small intestine. However, this local contraction serves to move food back and forth. This allows the subdivision continues constantly, break up, and mix the contents.

Segmentation motion facilitates the mixing of food with the secretion of intestinal small while allowing digestion mechanical. By thus, both to facilitate the absorption of nutrients through the digestion and reproduction of food towards the end of the stripe late digestion is slow.

Similarities Between Peristalsis and Segmentation Contractions

  • Peristalsis motion and segmentation motion are two types of contraction of muscle that occurs in channel digestion.
  • They are the movement of muscle that is not accidental.
  • Furthermore, they function for the movement of food through the digestive tract.
  • They also function for the mechanical digestion of food as well as mixing food with different secretions from the digestive tract.
  • Besides that, the muscles of the fine on the walls of the channel digestive do contraction this.
  • Reflex length, system nervous enteric, and peptides gastrointestinal controlling the movement of the muscles of this.

  • Peristalsis motion: peristalsis is contraction not intentional and relaxation of the muscles of the intestine, creating a movement like a wave, pushing the contents of the canal to the front.
  • Segmentation motion: segmentation is a contraction of the muscle back and forth, especially in the intestine small for the contraction of muscle smooth.

The Incident

  • Peristalsis motion: peristaltic mainly occurs in the esophagus.
  • segmentation motion: segmentation mainly occurs in small and large intestines.

Types of Muscles

  • Peristalsis motion: peristaltic occurs by contraction of the muscles of the circular.
  • Segmentation motion: segmentation occurs due to rhythmic contractions of the longitudinal muscles.

Movement Type

  • Peristalsis motion: peristaltic motion is the movement of one direction in the direction of the tail.
  • segmentation motion: segmentation motion is responsible for movement in both directions, allowing mixing which is great.

Propagation Speed

  • Peristalsis motion: peristaltic generates the multiplication of food – speed high.
  • segmentation motion: segmentation results in the multiplication of food is slow.


Peristalsis is a kind of contraction of the muscles that mainly occurs in the esophagus. In general, the circular muscles of the esophagus produce one- way movements for moving food. On the other hand, segmentation is another type of muscle contraction mainly occurring in the small intestine. However, longitudinal muscles in the small intestine produce alternating movements of food.

Besides that, it allows the mixing of food that is appropriate to the secretion of the intestinal little while facilitating the digestion of food by mechanical. Because it is, the difference main between peristalsis and segmentation is the kind of movement that they produce.
