The small intestine lies curled up in the abdomen, causing bowel loops are formed. The small intestine consists of three parts:

THE DUODENUM
is the first part of the small intestine from the stomach door (the sphincter muscle at the end of the stomach), where enzymes from the pancreas and bile from the liver stimulate the digestive system.

THE FASTING INTESTINAL
is the middle part of the small intestine between the Flexura duodenojejunalis and the ileum. In the fasting intestine and ileum where the vast majority of digestion and absorption of food components instead. The passage of food through the intestine and ileum fasting lasts 1 to 2 hours. The acidic, liquid food is converted in an alkaline substance. Almost all the nutrients to be withdrawn from here to the liquid, with the aid of enzymes in the intestinal fluid.

ILEUM
is the last part of the small intestine. The outlet of this latter part (the terminal ileum) in the large intestine. It is more a functional than an anatomical valve valve structure. Of the ileocecal valve (Valva ileocaecalis) ensure that the gut contents from flowing back.
