      - Nucleosidase
        
        A brush border enzyme,that breaks the bond between the sugar and the nitrogenous base of the nucleoside
  - - - Initiate mechanical digestion by forming ingested material into a wet mass called bolus
    - - Component of saliva, initiates the chemical digestion of starch
    - - Accomplishes swallowing, with assistance of mucus secreted in Saliva
    - - Transports the bolus from the pharynx to the stomach
    - - mixes the bolus with gastric secretions as smooth muscle contractions mix the bolus with the secretions to form chyme
    - - Finishes chemical digestion and is responsible for absorbing most of nutrients from food.
    - - Absorbs water and electrolytes from the remaining digested material and compacts it into feces

      - Medications
      - Liquids
