helps mix with the food with saliva in the mouth
Answer (1)
The tongue is a muscular organ in the mouth that plays a key role in the process of eating. When food enters the mouth, the tongue moves the food around, helping to mix it thoroughly with saliva. Saliva contains enzymes that begin the digestion of carbohydrates. Mixing food with saliva also moistens the food, making it easier to chew and swallow. Thus, the tongue facilitates both mechanical and chemical digestion at the very start of the digestive process.
