Where are carbohydrates broken down?

     The small intestine, pancreas, and liver.

    From there, the wall of the small intestine begins to make lactase, sucrase, and maltase. These enzymes break down the sugars even further into monosaccharides or single sugars. These sugars are the ones that are finally absorbed into the small intestine.  

Hope this Helps! :)
