The inside wall of the small intestine needs to be thin, with a really big surface area. This allows absorption to happen quickly and efficiently. If the small intestine had a thick wall and a small surface area, a lot of digested food might pass out of the body before it had a chance to be 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.nce these materials have been broken down, nutrient absorption can occur.
