How Your Digestive System Works is a new TED-Ed lesson. Like all TED-Ed lessons the graphics in the video are great. The content itself is rather basic and best suited for a middle school science classroom. If you want to extend the lesson I would recommend taking a look at Sponge Lab Biology's Interactive Build a Body.
On Sponge Lab Biology's Interactive Build a Body students assemble systems within the human body. Have your students try to correctly assemble the digestive system after watching the TED-Ed lesson about the digestive system.
