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.
Carbohydrates tend to leave the stomach rapidly and enter the small intestine; proteins leave the stomach less rapidly; and fats linger there the longest. The small intestine is the principal site of digestion and absorption. There, enzymes and secretions from the pancreas, liver, gallbladder, and the small intestine itself combine to break down nutrients so that they can be absorbed.
