Put the food in a blender to simulate mastication (chewing) and then put some vinegar in it in a pot on the stove and cook it. Cooking helps break down the food particles into an absorbable state, and that is the same as digestion. Next put the cooked food from the pot in a strainer, and anything that leaks out is absorbable nutrients. Finally squeeze the water out of the remaining stuff in the strainer, to simulate the function of the colon absorbing water, and squeeze your fist with the remaining ingredients like it is leaving the body. In other words, make the stuff squeeze out the bottom of your fist like you are doing a bowel movement. That is the entire course of the alimentary canal known as the gastrointestinal tract.

What body parts is not involved in mechanical digestion?
Chemical digestion takes place in the stomach, the intestines, (saliva or enzymes) these parts of your body also use mechanical digestion.
What type of digestion is produced by breaking down and chewing food?
Chemical digestion
What is the second stage of digestion?
it is digestion trololo
What does movement mean in reference to digestion?
the physical propulsion of food through the gastrointestinal tract (GI tract)
Could chemical digestion take place if mechanical digestion did not occur?
Mechanical digestion, i.e. your body breaking up the food into smaller pieces, is largely meant to speed chemical digestion up. We know that the rate at which the chemical reaction takes place is dependent on four things: the physical state of the reactants involved in the reaction, the temperature at which the reaction takes place, the concentration of the reactants, and the presence of a catalyst. Each influences the rate of reaction in different ways. Mechanical digestion breaks the food into smaller pieces, i.e. changes the physical state. With the larger pieces broken into smaller ones, more surface area is exposed. With greater surface area exposure, chemical digestion can take place much more rapidly. However, if for some reason you could get just huge chunks of food down your throat without chewing it, your stomach still churns (mechanical digestion) and the contractions in your intestines also help to break up food. So technically yes, chemical digestion would take place, but at a much slower and inefficient manner.
What part of digestion involves a physical change?
mechanical digestion
What type of change that occurs in mechanical digestion?
By definition mechanical digestion is a physical part of digestion.
What teeth do you use in physical digestion?
All teeth are used in physical digestion and break-down of food before swallowing.
What type of foods don't require chemical and physical digestion?
all foods require either physical or chemical digestion.
Is digestion a physical or chemical change?

What is the type of digestion the salivary glands have chemical physical both or neither?
Chemical digestion
is digestion of food physical of chemical?
both physical and chemical
What does mechanical digestion stand for?
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.
What is the breakdown of large food molecules into smaller molecules colled?
Physical digestion is the term for breaking down large food molecules into small molecules. Mechanical digestion and physical digestion mean the same thing.
