They are both a type of mechanical digestion that is involved in the gastrointestinal tract.
Peristalsis is the slow and gradual movement of food through the digestive system. The food is crushed and propelled in one direction as smooth muscle contracts and forces the food along the gastrointestinal tract.
Peristalsis is not to churn, but to slowly move food along towards the large intestine, however, segmentation is the local mixing of food with enzymes and intestinal juices (from pancreas etc). Therefore the food is mixed and and exposed to absorptive cells as it moves along.

∙ 13y agoThe difference between these two, lie in how the intestinal track works. Normally the intestine moves food by something called Peristalsis and segmentation as defined below:
Peristalsis : Peristalsis is a series of organized muscle contractions that occur throughout the digestive tract. Namely in the esophagous and small intestine
On the othe hand, segmentation motility* (*a fancy word for mobility) is a special movement of the small intestine to mix its contents by special contractions of these muscles.
In other words, peristalsis deals with propulsion while segmetation deals with mixing of food found in the digestive system.

What is the difference between cluster and segmentation?
see zyxo.wordpress.com/2010/07/17/the-difference-between-segmentation-and-clustering/ for a neat explanation.
What is the difference between metamerism and segmentation?
not sure
What are two mechanisms that control motility and secretion of the digestive system?
peristalsis and segmentation
What is segmentation and peristalsis?
This the way the movement occurs in smooth muscle. Peristalsis occurs in the intestine. Segmental movements occur there also but in large waves.
Which layer of the alimentary canal is responsible for segmentation and peristalsis?
the smooth muscles are responsible for perstalsis and segmentation, so that means its the muscularis externa. :)
What is the major difference between a hookworm Nematoda and an earthworm Annelid?
body segmentation
What is the difference between market research and market segmentation?
Market research helps you "identify" your market. Segmentation lets you "segment" your identified market into more refined groups. In short market research is more broad and segmentation is more refined.
Difference between market segmentation and consumer profiling?
Segmentation is often used in conjunction with customer profiling, but there are areas of difference. For instance, profiles are not suitable for identifying certain population segments: people with disabilities are usually split between multiple neighbourhood profiles. Likewise gender segmentation is rarely associated with neighbourhood. For other factors such as age and ethnicity, composite profiles can only support broad generalities.
What is the relationship between peristalsis and colon?
peristalsis moves feces through the colon.
The difference between expert classification and image segmentation?
image segmentation refers to clustering or grouping of homogeneous pixels into various groups while classification is next hierarchy which labell those clustered pixels as different classes..
Where are all the places mechanical digestion takes?
Mechanical digestion takes place in the mouth (chewing) and the stomach swishing stuff around (peristalsis) and more churning the small intestine (segmentation)
What movement continually mixes the food with digestive juices?
Segmentation is a muscle action that mixes chyme with digestive juices, while Peristalsis is a muscle action that moves food through the digestive system.
