The small intestine is the site of nutrient absorption. The pancreas assists the small intestine by releasing an alkaline and lots of enzymes, which break down carbohydrates, fat and protein in food. At the same time, the gall bladder releases bile to break down fat.
Once food is reduced to small particles, it is absorbed through the walls of the small intestine. The nutrients are then passed into the bloodstream.
