Answer:
Physiological process: Digestion
Step-by-step explanation:
Digestion is the process by which food is reduced to simpler compounds and these are used for the functioning of the body.
The mouth is where the process of digestion of food begins, especially the chemical digestion of carbohydrates. In it there are teeth that crunch the food and together with the tongue, wrap the pieces of food with saliva, which are produced and secreted by the salivary glands attached to the mouth, parotid, submaxillary and sublingual.
