Mechanical Digestion can be defined as the physical breakdown of food into smaller, more digestible pieces. But your probably wondering... What parts of the body actually have this awesome, useful feature? Well, it can be found in the...
Mouth: Teeth used to grind and cut food down while mouth repeatedly opens and shuts to chew (masticate) said food.
Stomach: Churning of the stomach helps mix in the food with your stomach acid to produce a substance called Liquid Chyme.
Small Intestine: Contractions of the small intestine mixes food with various enzymes (Intestinal, Pancreatic) and bile.
By the standards of body functions, this is actually pretty simple, since it's really just the contractions of various smooth muscles, like skeletal muscle contractions.
