Q

Where does the pancreatic duct travel?

A

Horizontally through the pancreas
leaves head of pancreas
turns inferiorly

17
Q

What happens to the pancreatic duct?

A

Joins with common bile duct

18
Q

What is formed by the common bile duct and pancreatic duct joining together?

A

Ampulla of vater

19
Q

How is the passage of pancreatic exocrine secretions into the duodenum controlled?

A

Sphincter of pancreatic duct

20
Q

What is the sphincter of pancreatic duct?

A

Smooth muscle thickening at end of pancreatic duct

21
Q

How does the sphincter of pancreatic duct control the passage of pancreatic exocrine secretions into the duodenum?

A

Contracts
to narrow the pancreatic duct
reduce passage of pancreatic exocrine secretions into ampulla of vater and hence duodenum

22
Q

How is the passage of both bile and pancreatic exocrine secretions into the duodenum controlled?

A

Sphincter of Oddi

23
Q

What is the sphincter of Oddi made up of?

A

Thickening of smooth muscle in ampulla of vater

24
Q

How does the sphincter of Oddi control the passage of both bile and pancreatic exocrine secretions into the duodenum?

A

Contracts
to narrow the ampulla of vater
reduces passage of both bile and pancreatic exocrine secretions into the duodenum
