The small intestine is made up of about twenty feet of tubes that loop around themselves to form the small intestine. The first foot of the small intestine is called the duodenum. This is where most of the digestion occurs. The paste-like liquid moves from the stomach to the duodenum where the paste is mixed with enzymes and chimes. The duodenum also receives digestive juices from the pancreas and bile from the liver. Once food leaves the duodenum, it is ready to be absorbed into the blood vessels and used for various purposes throughout the body. The next part of the small intestine where food is absorbed into the body is called the epithelium. The epithelium is similar to a fluffy towel in that it has large folds and also has small finger-like growths where nutrients are grabbed and transported into blood vessels. Anything that is not absorbed in the small intestine moves into the large intestine (2012, Pg.
