Segmentation is a squeezing motion of the circular layer of smooth muscle in the small intestine.
<h3>What is segmentation in the small intestine?</h3>
Segmentation, which mostly affects the small intestine, is made up of localized contractions of the Gastro-Intestinal tract's circular muscle. These contractions separate out little portions of the intestine, allowing their contents to move back and forth while being continuously divided, broken up, and mixed.
Our intestines' circular muscles contract during segmentation to churn food back and forth, rather like a washing machine. This churning helps break down food into tiny bits for digestion by allowing it to mix with gastric secretions in the intestines. By bringing chyme into contact with the intestinal walls during segmentation, the technique also helps to increase absorption.
