What is Peristalsis?
The contraction and relaxation of food in the esophagus and food pipe, which forces the food down the track and into the stomach, is referred to as peristalsis. For food to pass down the stomach and feces to pass down the anus, this involuntary movement is required.
After full swallowing of the food, the esophagus initiates the peristaltic movement, which involves the reflexive contraction of the circular and longitudinal muscles mainly in the digestive sites and occasionally in hollow tubes that produce progressive wave-like contractions. Peristalsis happens in the stomach, intestines, and esophagus. Depending on where the organs are located, the waves that go through them might be long, short, continuous, or intermittent.
Functions of Peristalsis
The following are the functions of peristalsis:
- Transport of Food: Food and liquids are moved through the digestive process via peristalsis. Food is moved from the esophagus to the stomach by it. Food is also transferred from the stomach to the small intestine by it.
- Digestion: Digestion depends on peristalsis. Eating and defecating would be impossible without it.
- Digestive Health: The health of the digestive system depends on peristalsis progressing slowly and steadily.
Difference Between Peristalsis and Segmentation
Peristalsis and Segmentation are two different types of muscle contractions that take place in the gastrointestinal system. They are responsible for the transportation of food through the gastrointestinal tract. The primary difference between segmentation and peristalsis is that segmentation allows for greater mixing because it moves in both directions while peristalsis only moves in one direction. Moreover, segmentation primarily takes place in the small and large intestines, whereas peristalsis primarily happens in the esophagus.
