The small intestine is responsible for most of your food digestion and all of your food absorption. The duodenum is the first section and is about a foot long. It digests all types of food (carbohydrates, proteins, and fats) with the help of pancreatic juices. The duodenum, along with the jejunem and the ileum, absorb the nutrients from the digested food and transfer them into the blood stream. You can live without your stomach, but you cannot live without your small intestines.
