The mechanical breakdown of food starts with the saliva in your mouth.
Chewing begins mechanical breakdown of food through mastication
The digestive process begins in the oral cavity, with the mechanical breakdown of material by the teeth and tongue and some sugar breakdown through the actions of amylase in the saliva.

The mouth and the stomach are two anatomical regions involved in the mechanical breakdown of food. In the mouth, teeth mechanically break down food into smaller pieces through mastication. In the stomach, muscular contractions churn and mix food with digestive juices to further break it down into a semi-liquid state.
Mouth. Mastication and saliva begins the food break down process
Digestion of cereal begins in the mouth. Mastication--chewing--breaks down the food. Saliva begins to break down carbohydrates contained in cereal grains. Digestion of cereal along with the milk continues in the stomach and small intestines.
salivary glands, then esophogus, then stomach, (with help of pencreas, liver, and galbladder), then small intestine, then large intestine, and finally, the colon and anus. Taa-Daa! :) ---------------------------------------------------------------------------------------------- The mouth.
the tongue.
The action that forces food into the digestive tract is swallowing. This begins with the tongue after mastication (chewing).
Digestion begins in the mouth. Mechanical digestion begins with the chewing of food. Chemical digestion also begins in the mouth with the enzymes been produced and used to break down the food.
First, chewing, or mastication, of the food occurs, this is where the teeth break down the food into smaller pieces. Then the saliva starts to break down the food into a paste-like substance that can be swallowed.
