The duodenum is the first part of the small intestine. It follows the stomach and extends into the jejunum and then the ileum
, the final part of the intestine. It surrounds the pancreas
from which it receives secretions in the form of pancreatic enzymes
; it also receives bile
from the gallbladder. It is in the duodenum that many metabolites and nutrients are absorbed such as calcium, iron, vitamins
, and lipids
. The duodenum may be at the center of some diseases
such as ulcers due to the presence of a bacterium, Helicobacter pylori, or stenosis.
