The major duodenal papilla is situated in the second part of the duodenum, 7–10 cm from the pylorus, at the level of the second or third lumbar vertebrae. It is surrounded by the sphincter of Oddi , a circular muscle, and receives a mixture of pancreatic enzymes and bile from the Ampulla of Vater , which drains both the pancreatic duct and ...
The common duct then opens medially into the descending part of the duodenum at the major duodenal papilla. The common duct usually measures 2-10mm in length. [1] The ampulla of Vater is an important landmark halfway along the second part of the duodenum marking the transition from foregut to midgut. [citation needed]
The duodenum precedes the jejunum and ileum and is the shortest part of the small intestine. In human beings, the duodenum is a hollow jointed tube about 25–38 centimetres (10–15 inches) long connecting the stomach to the middle part of the small intestine. [4] [5] It begins with the duodenal bulb and ends at the suspensory muscle of ...
The bile duct is some 6–8 cm long, and normally up to 8 mm in diameter. [4]Its proximal supraduodenal part is situated within the free edge of the lesser omentum.Its middle retroduodenal part is oriented inferiorly and right-ward, and is situated posterior to the first part of the duodenum, and anterior to the inferior vena cava.
The minor duodenal papilla is contained within the second part of the duodenum. It is situated 2 cm proximal to the major duodenal papilla, and thus 5–8 cm from the opening of the pylorus. The gastroduodenal artery lies posterior. [1]

Because of your brain's connection to the stomach through the Enteric Nervous System and the stomach's involvement in digestion, stress is also a common irritant of the digestive system. It can ...
In the other 30% of people, it drains into the main pancreatic duct, which drains into the duodenum via the major duodenal papilla. The main pancreatic duct and the accessory duct both eventually—either directly or indirectly—connect to the second part ('D2', the vertical segment) of the duodenum. It is named for Giovanni Domenico Santorini.
