QuestionSBA
QuestionChoice
The common bile duct transports bile from the gallbladder. It fuses with the pancreatic duct to form the ampulla of Vater which then passes through the sphincter of Oddi and into the duodenum. If there is a high concentration of fatty food in the duodenum, the sphincter of Oddi may relax to allow bile (and pancreatic juice) to pass through the ampulla of Vater into the duodenum to emulsify fats.

Common bile duct
QuestionChoice
The duct of Santorini is an accessory duct from the main pancreatic duct (Wirsung duct). It exits into the duodenum around 2cm superiorly to the ampulla of Vater. This usually acts only as a safety feature for if the Wirsung duct is unable to drain pancreatic juice, and is usually largely non-functioning.

Duct of Santorini
QuestionChoice
The sphincter of Oddi is a muscular valve which surrounds the exit of the common bile duct and pancreatic duct, which join to create the Ampulla of Vater which exits into the duodenum. When fatty foods move into the duodenum, bile and pancreatic juices are needed to digest them. Therefore, the sphincter of Oddi relaxes to allow bile and pancreatic juice to enter the duodenum via the ampulla of Vater.

a
Sphincter of Oddi
QuestionChoice
The ampulla of Vater is the point where the bile duct and pancreatic duct join and pass into the duodenum. It is surrounded by the sphincter of Oddi, which relaxes to allow bile and pancreatic juice to pass into the duodenum when fatty food is present. The ampulla of Vater itself does not relax or contract, and is controlled by the Sphincter of Oddi.

b
Ampulla of Vater
QuestionChoice
The Wirsung duct is the main pancreatic duct. It joins with the common bile duct to create the ampulla of Vater which allows bile and pancreatic juice to flow into the duodenum. However, the flow of bile into the duodenum when fatty food is present in the duodenum is controlled by the sphincter of Oddi - which the ampulla of Vater flows through.
