Importance of mucus on the walls of food pipe : 

1. The walls of the food pipe secrete a slippery substance called mucus. 

2. Mucus lubricates and protects the oesophgeal walls from damage.

3. This helps the food bolus to slide down easily. 

4. Besides this the saliva in the bolus also helps in easy movement.
