The small intestine is the longest portion of the digestive tract – it is more than 6 meters long and is located within the middle of the abdomen. It has three sections, the duodenum, jejunum and ileum.
Small intestine has an important function in digestion of fats, proteins and carbohydrates contained in the foods you consume. The resulting nutrients produced are absorbed through the lining of the small intestine and transferred to the bloodstream.
