From morning to night, the tongue is hard at work. It helps us speak, chew, produce saliva and analyze food. Hundreds of thousands of taste cells detect five flavor profiles, giving us clues about what we’re eating. And the tongue’s color says a lot about our health.

What's inside us? Our organs, of course. But they don't always get the attention they deserve. The series "Organized" aims to portray the organs of the human body with 3D animations in a vivid, funny and entertaining way helping viewers of all ages understand their special characteristics and how they work.
