    - - a mixing/holding chamber that helps mix food into tiny particles through chemical and mechanical digestion
    - - helps food turn into bolus by masticating/lubricating food with saliva
    - - breaks down food from the stomach and absorbs much of the nutrients from the food
    - - water/sat is absorbed as well as the storage and defecation of feces
    - - pass food from the mouth to the stomach
