Food digestion and nutrient absorption take place primarily in the small intestine, according to eMedicineHealth. Nutrient absorption is facilitated by villi and microvilli, fingerlike projections from the intestinal wall that serve to increase the surface area of the intestine so that nutrients can be fully absorbed.
Although there is preliminary breakdown of starches in the mouth and proteins in the stomach, the bulk of digestion and absorption takes place in the small intestine. Digestive enzymes are produced in the pancreas and released to the small intestine as a package.
