This series (originally created in French) explains processes in the human body, and in particular those related to cells and reproduction. We begin with the origin of the first cell—the source of all life on Earth!

What is a cell made of, and how many of them are there in the human body? And what is the “primordial soup” from which all life on Earth emerged?

Red and white blood cells, fats, carbohydrates, and more! They are all anthropomorphized in this zany animated look at how human cells are formed.

The journey continues inside of the cell, where one of the operators take a few elements along on a tour of all of the different respiratory processes.

In this final segment detailing the goings-on within a human cell, we learn about what happens when there’s a skin injury.
