Bile emulsifies lipids in the small intestine. No food is absorbed until the small intestine.What are the “essentials” for the human diet? What are the main divisions vertebrate (mammalian) digestive systems, what processes go on in these divisions?Food digestion occurs in much the same way in all vertebrates and many invertebrates. Which describes this common process?
