ANSWER:
The salivary amylase makes food into balls. The process of digestion starts in the mouth when the food eaten is chewed.
EXPLANATION:
- In the mouth, the "salivary glands" secrete an enzyme called amylase that breaks down the food or long starch molecules into maltose.
- When the food is ready to be swallowed, it is "gathered into a ball" called bolus.
- The bolus is then sent to the pharynx from where the food goes to the oesophagus and eventually to the stomach.
