Question:

Which of the following structures prevents the back flow of faecal matter?

Options:

1. Cardiac sphincter
2. Pyloric sphincter
3. Ileo-caecal valve
4. Sphincter of Oddi

Solution:

The ileo-caecal valve is located at the junction of the small intestine and large intestine, and it prevents the backflow of faecal matter from the large intestine into the small intestine. The cardiac sphincter is located at the junction of the oesophagus and stomach, and it prevents the backflow of stomach contents into the oesophagus. The pyloric sphincter is located at the junction of the stomach and small intestine, and it regulates the release of chyme from the stomach into the small intestine. The sphincter of Oddi is located at the junction of the common bile duct and the pancreatic duct with the duodenum, and it regulates the release of bile and pancreatic enzymes into the duodenum.
