[#] 12 [Description and Function] The duodenum is the first section of the twenty two foot long small intestine. It starts at the pyloric sphincter of the stomach and runs about 10 inches. The duodenum is largely responsible for the continuing food breaking-down process (fats are bombarded with bile), with the jejunum and ileum mainly responsible for the transfer of nutrients into the bloodstream.
