The duodenum, the first and shortest section of the small intestine, is a key organ in the digestive system. The small intestine’s most important function is to digest nutrients and pass them into the blood vessels—located in the intestinal wall—for absorption of the nutrients into the bloodstream. Duodenum Functions The duodenum continues the process of digestion of food that begins in the stomach. Its main function is to receive the chyme which is a combination of partially digested food and stomach acids. The chyme is released into the duodenum through pylorus, which is a small valve located between the stomach and the duodenum. The liver has so many functions but the main digestive function is making bile. The gallbladder stores bile made from the liver.
