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.
Once these materials have been broken down, nutrient absorption can occur. As food is processed along the digestive tract, most of the nutrients are absorbed through the walls of the small intestines. The nutrients are carried into the bloodstream where they can travel to all parts of the body. Other substances that are absorbed during digestion include vitamins, water, and salt.
