Question

Bile can be prevented to pass into duodenum by

• A. Pyloric valve
• B. Sphincter of Boyden
• C. Sphincter of Oddi
• D. Cardiac sphincter

Answer 1

The correct option is C Sphincter of Oddi

The sphincter of Oddi is the muscular valve surrounding the exit of the bile duct and pancreatic duct into the duodenum. The sphincter is normally closed, opening only in response to a meal so that digestive juices can enter the duodenum and mix with food for digestion. So bile can be prevented to pass into the duodenum by sphincter of oddi.

So, the correct answer is 'Sphincter of Oddi'
