chemical digestion due to the saliva breaking down food or other things in your mouth.

Were does chemical digestion take place
When your body breaks down food into nutrients, chemical digestion is taking place. In contrast, physical digestion breaks down food mechanically into smaller particles.
Its a chemical change.
Long time ago when I studied this but I think you are looking at physical and chemical. Physical digestion is masticulation, chewing, crushing, grinding etc and takes place in the mouth. Chemical digestion is the breakdown of foods by substances such as bile acids etc. This process also starts in the mouth as saliva contains some digestive acids, but in the main part takes place in the large intestine.

chemical digestion
Mechanical digestion, i.e. your body breaking up the food into smaller pieces, is largely meant to speed chemical digestion up. We know that the rate at which the chemical reaction takes place is dependent on four things: the physical state of the reactants involved in the reaction, the temperature at which the reaction takes place, the concentration of the reactants, and the presence of a catalyst. Each influences the rate of reaction in different ways. Mechanical digestion breaks the food into smaller pieces, i.e. changes the physical state. With the larger pieces broken into smaller ones, more surface area is exposed. With greater surface area exposure, chemical digestion can take place much more rapidly. However, if for some reason you could get just huge chunks of food down your throat without chewing it, your stomach still churns (mechanical digestion) and the contractions in your intestines also help to break up food. So technically yes, chemical digestion would take place, but at a much slower and inefficient manner.
In the Mouth then the second is the Stomach
welll it takes place in both mechanical and chemical
Digestion of food is a combination of physical and chemical changes. Physical changes occur as food is broken down into smaller pieces through chewing and grinding. Chemical changes take place as enzymes in the digestive system break down food into simpler molecules that can be absorbed by the body.
chemical digestion takes place in the small intestine large intestine,mouth and stomach. Nutrients are absorbed in the small intestine and minerals in the large intestine.
