In the belittled intestine chyme is mixed with a digestive juice from the pancreas called pancreatic juice. Bile, which is made in the liver, is excessively mixed with chyme. The bile helps lipase break down fats (butter and dissociate of the beef) into fat person acids and glycerol. The chyme is then pushed along the small intestine by peristalsis. As the chyme is digested, nutrients from the beef sandwich are released and absorbed through the villi and read/write head into the blood stream. The villi are part of the intestinal wall and suppuration the area for absorption and so therefore they speed up the absorption of nutrients.
