Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. Segmentation is another kind of involuntary muscle movement that occurs in your digestive system.

2. Introduction
Peristalsis is a series of wave-like
muscle contractions that move
food through the digestive tract.

3. Esophageal
Peristalsis
Peristaltic waves in esophagus start
from the upper position of the tube and
pass into the complete length and impel
the food into the stomach. This could
be termed as Esophageal Peristalsis.

4. Intestinal
Peristalsis
The stimulation of smooth muscle
tissues for the existence of food
particles in the small intestine is
responsible for contractions that
travel from the restorative point in
both directions is termed as
Intestinal Peristalsis.

5. Segmentation is another kind of involuntary muscle movement that occurs in your
digestive system. But unlike peristalsis, which occurs throughout your GI tract,
segmentation occurs mainly in your intestines. Segmentation activates circular
muscles in your intestines that contract to move food back and forth, a bit like the
churning of a washing machine. This churning gives food in the intestines a chance to
mix with gastric juices and helps break it down into smaller pieces for digestion.
Segmentation slows the progress of food through your GI tract somewhat, but
peristalsis continues to move it gradually along.
What is the difference between peristalsis
and segmentation?

contribute to the following conditions:
Alteration in normal
urination
Deficiency in
swallowing food
Slow peristalsis
causes constipation
