Circular Folds, Villi and Microvilli in Small Intestine -

Circular Folds:

  • These are also called folds of Kerckring or plica circulare. 
  • These are deep ridges in the mucosa and submucosa.
  • They begin near the proximal part of the duodenum and end near the middle of the ileum. 
  • These folds facilitate absorption.
  • Their shape causes the chyme to spiral, rather than move in a straight line, through the small intestine. 
  • Spiraling slows the movement of chyme and provides the time needed for nutrients to be fully absorbed.
