How does saliva help in the digestion process?

Salivary Glands It has a cleansing action on the teeth. It moistens and lubricates food during mastication and swallowing. It dissolves certain molecules so that food can be tasted. It begins the chemical digestion of starches through the action of amylase, which breaks down polysaccharides into disaccharides.

How tongue and salivary gland helps in digestion?

These structures make up the mouth and play a key role in the first step of digestion: ingestion. This is where the teeth and tongue work with salivary glands to break down food into small masses that can be swallowed, preparing them for the journey through the alimentary canal.
