Chewing begins mechanical breakdown of food through mastication
The mechanical breakdown of food starts with the saliva in your mouth.
mechanical breakdown
Mechanical breakdown makes food smaller so it wasn't be so large for the chemical breakdown.
a mechanical breakdown is when you manualy breakdown something,without using any objects. for example chewing your food is a mechanical brekdown or ripping a paper. And when you are breaking it down it fells like you do not feel anything.
The mouth is involved in both chemical and mechanical breakdown of food. Mechanical breakdown occurs through chewing and mixing with saliva, while chemical breakdown is initiated by enzymes in saliva that start breaking down carbohydrates.
mechanical breakdown
Mechanical breakdown helps chemical breakdown because when you chew, chemical breakdown is going on all at the same time. So, that is going to chemical because if you didn't have saliva (chemical breakdown) if would take real long to digest your food.
Saliva
Mastication, commonly known as chewing, is the term for the mechanical breakdown of food in the mouth.
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.
2 primary actions that I'm aware of. Mechanical breakdown and breakdown by amylase.
Mechanical digestion is the physical breakdown of food into smaller pieces through chewing and mixing by the muscular contractions in the digestive tract. It primarily occurs in the mouth through chewing and in the stomach through churning actions.
