One lucky sperm has made it into the egg – now the chromosomes from the sperm and the egg can start to link up.

Cell division is now in full swing, and inside the embryo, the organs are being formed! All the cells now have to reach the places where they are needed.

The formation of the embryo is in full swing, and the cells are working diligently to create all of the different body parts!

More building blocks are needed to form the growing embryo — and the chromosome department is hard at work!

The last segment of this video focuses on gestation: Over the course of nine months, a single, fertilized egg becomes a baby!

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.

A few nasty viruses have managed to gain entry into the cells. But the white blood cells can handle them!

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