What term describes the physical breakdown of foods?

Explanation:
Physical breakdown of foods is called mechanical processing. This involves the actual chewing and grinding in the mouth and the muscular mixing and squashing of food in the stomach to reduce particle size. It’s different from chemical digestion, which uses enzymes to break chemical bonds, while absorption is the uptake of nutrients into the bloodstream and secretion is the release of digestive fluids. So mechanical processing best fits the description of the physical breakdown.
