Intestine – Duodenum Overview
Anatomy
The duodenum belongs to the digestive tract. It is the first section of the small intestine, which follows the pylorus and precedes the ileum and jejunum. The name duodenum is from the Latin duodenum digitorum, or “twelve fingers’ breadth”.
The bile duct and the pancreas duct empty into the duodenum. Here, most chemical digestion takes place.
The beginning section of the duodenum is widened into an “onion shape” bulbus duodeni) and is covered by ectodermal (Cerebral Cortex directed) squamous epithelium tissue. The remaining small intestine lining consists of ciliated duodenum epithelium tissue and is of endodermal origin.
