oral cavity and stomach
The mouth is where food is chewed.
The mouth, specifically the teeth, breaks down food mechanically through the process of chewing. The stomach also contributes to mechanical breakdown through muscle contractions that help mix and churn food.
Oral Cavity
Starts in the oral cavity and then the stomach.

When your body breaks down food into nutrients, chemical digestion is taking place. In contrast, physical digestion breaks down food mechanically into smaller particles.
The stomach mechanically/chemically breaks down food. It adds acid and mixes it into the food.
Your GI, or gastrointestinal, tract breaks down foods. The make-up of the food you ingest will determine how it's broken down. Your mouth mechanically (chewing) breaks down all food and chemically breaks down carbohydrates. Your stomach breaks down proteins and fats. Your small intestine breaks down everything else via pancreatic acids and enzymes. Majority of carbohydrates break down in the small intestine.
The stomach mechanically breaks down food through a process called mechanical digestion, which involves the churning and mixing of food with gastric juices. This action helps to break down larger food particles into smaller pieces, making it easier for digestion and absorption in the intestines.
Fats and oils are broken down into solublpubstances andtgo
Chewing, or mastication, uses the teeth to mechanically tear apart the food. Saliva contains amylase, an enzyme that breaks down starches in the mouth.
Does the liver mechanically break down food or does it chemically do it? It's not a muscle so it doesn't break down food mechanically, but it does secrete chemicals that help to break food down, like bile, which is stored in the gall bladder and released to help break down fats and make them more soluble so that they can be absorbed by the body.
