Mechanical digestion physically breaks food into smaller pieces.Chemical digestion breaks apart food an molecular level through chemical reaction. Once food is digested, its nutrients are absorbed into the body and carried to the cells.
Both types of digestion start in the mouth. the teeth are responsible for mechanical digestion by grinding and chewing food to break it into smaller pieces. This makes it easier for chemical digestion to occur.Saliva in the mouth has special chemicals into the called enzymes an enzymes is a type of protein that regulates nearly all chemical reaction in cells.
