Question

What is segmentation in digestion?

Answer 1

Segmentation in digestion:

1. Segmentation is a muscular activity that divides and mixes the chyme by alternating between backward and forward movement of the gastrointestinal tract (GI) contents.
2. Segmentation is predominantly observed in the small intestine and large intestine of the GI tract.
3. This process promotes the contact of chyme with the intestinal wall to aid in absorption.
