What type of organ is a gallbladder?
Intraperitoneal
What is the biliary tree?
The series of ducts which stem from the liver and gallbladder to move bile towards the duodenum
What is the function of the gallbladder?
Stores bile
What structure is at number 1?
Neck
What structure is at number 2?
Body
What structure is at number 3?
Fundus
What structure is at number 1?
CYSTIC DUCT
What is role of the cystic duct?
Allows bile from liver to enter gallbladder to be stored
What structure is at number 1?
Right hepatic duct
What structure is at number 2?
Left hepatic duct
What structure is at number 3?
Common hepatic duct
What structure is at number 4?
Bile duct
What happens at the major duodenal papilla?
The series of ducts via which the exocrine cells of the pancreas secrete their enzymes into the duodenum end at the duodenal papilla.
Then the enzymes mix with the bile from the gallbladder here also.
What structure is formed when the pancreatic duct and bile duct join?
Hepatopancreatic duct
Where does the hepatopancreatic duct drain into?
Duodenum via the major duodenal papilla
What is the function of the minor duodenal papilla?
Point at which accessory pancreatic duct empties contents into duodenum
- Not usually functional - usually embryological remnant or degraded as with accessory duct.
What structure is at number 1
Accessory pancreatic duct
What structure is at number 2
Pancreatic duct
What structure is at number 1?
Hepatopancreatic duct
What structure is at number 1?
Minor duodenal papilla
What structure is at number 2?
Major duodenal papilla
What type of organ is the pancreas?
Mostly retroperitoneal except for tail which is intraperitoneal
How does the pancreas being mostly retroperitoneal affect how pain is felt from it
Pain is usually a dull ache towards the middle of back

What structure is at number 4 ?
Ascending part of duodenum
What structure is at number 5 ?
