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.
The small intestine or small bowel is the part of the gastrointestinal tract between the stomach and the large intestine, and is where most of the digestion and absorption of food takes place. The small intestine has three distinct regions â the duodenum, jejunum, and ileum. The duodenum receives bile and pancreatic juice through the pancreatic duct, controlled by the sphincter of Oddi. The primary function of the small intestine is the absorption of nutrients and minerals from food. This article is primarily about the human gastrointestinal tract. The information about its processes is directly applicable to most placental mammals.
