where is the villi located in the digestive system?
chorion
most food digestion takes place in the small intestine. segmentation contractions act to mix and move the chyme more slowly in the small intestine allowing more time for absorption (and these continue in the large intestine). in the duodenum, pancreatic lipase is secreted together with a co-enzyme, colipase to further digest the fat content of the chyme. from this breakdown, smaller particles of emulsified fats called chylomicrons are produced. there are also digestive cells called enterocytes lining the intestines (the majority being in the small intestine). they are unusual cells in that they have villi on their surface which in turn have innumerable microvilli on their surface. all these villi make for a greater surface area, not only for the absorption of chyme but also for its further digestion by large numbers of digestive enzymes present on the microvilli.
