The brain is not directly involved in mechanical digestion. It plays a role in initiating the digestive process through signals but does not physically participate in breaking down food.

There are many. Digestion is a twofold process; physical digestion and enzymatic digestion. Physical digestion is the act of eating food to break it into smaller parts. Enzymatic digestion is where enzymes (chemical compounds produced by the body) break the food down at a molecular level. Enzymes include salivary amylase, pepsin, lipase, trypsin and many, many more.
Respiratory, Digestion, etc.
The small intestine is the organ responsible for both chemical digestion and absorption of nutrients from food. Enzymes and bile break down the food, while nutrients are absorbed through the small intestine's lining into the bloodstream for distribution to the body's cells.
Nutrients are substances that are absorbed by the body through the process of digestion.
Mechanical digestion. The actual grinding and physical breaking down of food. Chemical digestion breaks down food using chemicals/enyzyms and chemical reactions.
Digestion begins in the mouth right after ingestion. There is mechanical and chemical digestion. Your teeth breaks up the food into smaller pieces (mechanical digestion) and your saliva contains salivary amylase which digests starch into maltose (chemical digestion).
The chemical reaction that is also called digestion is called hydrolysis. In this process, water is used to break down complex molecules into simpler ones that can be absorbed by the body for energy and nutrients.
