TED Ed Lessons Worth Sharing presents “You are your microbes”, an animated movie where the researchers Jessica Green and Karen Guillemin show, in an easy way, that the human body harbors a huge quantity of bacteria organized in communities. The relevance of these microbial communities is essential, they explained, because it is thanks to their activity that our body works properly.

The hundreds of trillions of bacteria living in our digestive system take an important presence in this video. The film explains, for instance, which are the different functions of the microorganisms making up or gut microbiota and how the food we eat can affect our health.

We hope you enjoy this video as much as we did.
