The answer is mechanical digestion. In mouth, it's mastication, or chewing.
mechanical
The purpose of chewing is to break down food. grinding is an action that occurs in the teeth anyway, using molars
It chew food in to small pieces and adds saliva for digestion. The process of digestion is to take large food particles and break them down into small food particles. Chewing mechanically reduces the size of the food particles. The saliva helps breaks down starch into sugar.
To break down large food particles into smaller ones, so that the surface area of the particles is increased and then can be acted on by digestive enzymes and thus absorbed by cells and then excreted as faeces.NOTE: Chemical digestion is really just a fancy name for digestion. Mechanical digestion is actually the chewing of food particles (the eating).Source: nature of biology book 1 (3rd edition).
chemical digestion is breaking down with saliva, and mechanical digestion is chewing...(break down with chew!):):P
our teeth break down food physically which is called mechanical break down
Mechanical digestion stands for the break down of food by chewing. Mechanical digestion is the physical part of the digestion process of the human body.
mechanical grinding of food, chemical break down
This form of digestion starts in the mouth with the salivary gland witch break down food
Physical: Chewing to make the food particles smaller. Chemical: Reactions with enzymes to break down the food so the body can use it.
"chemical" or "chemical digestion"
Teeth are useful in chewing food. The process of chewing helps to break the bigger chunks of food into smaller easily digestible pieces.This helps in easy digestion of food.
