Brush-border enzymes
Mechanical digestion in the small intestine involves
Segmentation, migrating motility complex
What is segmentations
It is contractions which mix chyme with digestive juices without pushing the intestinal contents along the tract.

In chemical digestion chyme entering the small intestine contains partially digested carbohydrates, proteins, and lipids. The completion of the digestion of these substances is a collective effort of
Pancreatic juices ( secreted by the pancreas), bile( secreted by the liver) and intestinal juice ( secreted by the small intestine)
What enzymes and digestive juices help in the digestion of carbohydrates
Salivary amylase, pancreatic amylase, brush-border enzymes
What enzymes and digestive juice help in the digestion of proteins
Pepsin, and pancreatic juice
What enzymes and digestive juice help with the digestion of lipids
Lingual lipase, gastric lipase, pancreatic lipase and bile
