Answer:
Saliva
Saliva initiates the process of digestion in the mouth. The food substance which gets mixed with the food in the mouth during chewing by teeth is saliva. It acts as digestive juice and softens the food, which further leads to the easy process of digestion. It is secreted by salivary glands.
Composition Of Saliva-
- Water
- Mucous
- Lysozymes
- Salivary amylase
Functions of Saliva-
- Mucus- moistens the food and helps in easy swallowing.
- Lysozymes- kills any pathogens present in the food.
- Salivary amylase- helps in the chemical digestion of food. Salivary amylase acts on starch present in the food and breaks it into maltose and dextrins.
