Digestion can be mechanical or chemical. Mechanical digestion is the process of physically (i.e. not involving biochemical enzyme) breaking food down into smaller pieces, creating a greater surface area for chemical digestion to take place. Examples of mechanical digestion include the churning motion of your stomach and obviously, the chewing process of your mouth. Chemical digestion, on the other hand, requires the presences of enzymes to trigger chemical reaction and break the food particles down to simpler substances. Examples include the salivary amylase breaking down sugar, stomach acid and gastric enzymes breaking down proteins, and the lipase breaking down lipids in the small intestine.
Chemical Digestion. Mechanical digestion is the chewing of your food while chemical digestion is the processes that further break down the food like your saliva and stomach acids.
When food is put into your mouth, the process of digestion begins. Chewing breaks down the food into smaller pieces, mixing it with saliva that contains enzymes to start breaking down carbohydrates. This prepares the food for swallowing and further digestion in the stomach and intestines.
Mechanical digestion is produced by breaking down and chewing food. This process involves the physical breakdown of food into smaller pieces that can be further digested and absorbed by the body.

Mechanical Digestion
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.
Yes, that is what mechanical digestion is. §§
Mechanical, of course.. If you experience your saliva deteriorating your food any time soon, let me know. Actually, saliva is there to help break down carbohydrates. The teeth in the mouth also digest food mechanically. In other words, the mouth uses both chemical and mechanical digestion to break down food.
Mechanical digestion starts when food is chewed physically by the teeth (grinding and tearing the food), and the remaining steps of digestion continue from then on.
Mechanical digestion must come first because it helps break down food
