Question

Once the undigested and unabsorbed substances enter the caecum, their backflow is prevented by ______.

Options

• Ileo-caecal valve

• Gastro-oesophageal sphincter

• Pyloric sphincter

• Sphincter of Oddi

Answer 1

Once the undigested and unabsorbed substances enter the caecum, their backflow is prevented by ileo-caecal valve.

Explanation:

The ileo-caecal valve is a sphincter connecting the ileum and caecum. The tiny intestine is referred to as the ileum, whereas the large intestine is called the caecum. It prevents undigested and unabsorbed compounds from entering the caecum and ensures proper digestion.
