Current Question (ID: 14250)

Question:

What prevents the backflow of fecal matter into the small intestine?

Options:

1. Ileo-caecal valve
2. Sphincter of Boyden
3. Meckel's diverticulum
4. Plicae semilunaris

Solution:

The ileo-caecal valve is a sphincter-like structure that separates the small intestine and large intestine. It prevents the backflow of fecal matter from the large intestine into the small intestine. The other options listed are not related to the prevention of backflow of fecal matter into the small intestine. Sphincter of Boyden is not a known anatomical structure, Meckel's diverticulum is an outpouching of the small intestine, and plicae semilunaris are folds in the mucous membrane of the colon.
