All teeth are used in physical digestion and break-down of food before swallowing.
mechanical digestion is with your teeth , chemical digestion is in your stomach and small intestine.
Teeth are involved in the mechanical digestion process. If they are not healthy they will not work properly to chew food.
Digestion involves both physical and chemical changes. The teeth crush food into smaller particles, which is a physical change, whereas the saliva, stomach, gall bladder, and pancreas contain chemicals that break down food chemically in the mouth, stomach, and small intestines.
That would be mechanical digestion.
To chew the food.
mechanical digestion
So they can chew (to prevent choking) and enzymes (saliva-for digestion) for digestion.
By definition mechanical digestion is a physical part of digestion.
Teeth help by mechanical digestion, which is breaking the food in smaller pieces in order for the saliva to cover it and make it easier to digest.
our teeth break down food physically which is called mechanical break down
Both:Enzymes in saliva chemically chop starches down into simple sugars (i.e. monosaccharides and disaccharides).The teeth mechanically crush and chop the food into smaller pieces.
Chemical digestion takes place in the stomach, the intestines, (saliva or enzymes) these parts of your body also use mechanical digestion.
