duodenum The first part – about 25 cm long – of the small intestine, connecting the stomach to the ileum. The duodenum receives chyme from the stomach through the pyloric sphincter. It also receives fluids from the pancreas and gall bladder via the common bile duct. The duodenum neutralizes the acidic chyme and mixes it with pancreatic, biliary, and intestinal secretions before passing it on to the jejunum.
