The small intestine is where 90 percent of digestion and absorption takes place. The other 10 percent taking place in the stomach and large intestine. Once broken down the nutrients are absorbed by the inner walls of the small intestine into the blood stream. The nutrients are rendered small enough so that they may pass or be transported, across the epithelial cells of the gastrointestinal tract. The nutrients are absorbed by processes of simple passive diffusion, facilitated diffusion, primary active transport or secondary active transport.
