Answer: The saliva in your mouth helps to break down starch of the roti and dal into sugars that are easier to digest. The tongue helps to push the food towards your teeth and helps to mix the food with saliva and then enables you to swallow it. After the food is swallowed, it slides down the pharynx into the oesophagus.
