The answer is **all of the above**.<br /><br />Digestion involves both *mechanical* breakdown (like chewing and churning in the stomach) and *chemical* breakdown (via enzymes) of food into smaller molecules. These smaller molecules are then *absorbed* into the bloodstream so the body can use them.<br />
