How are our bodies created to fight off viruses and infections?

 Last term the class learned about how the body's defense systems protect us and fight off sickness. 

The students had the task of creating a model to help explain an aspect that they were interested in.

Here are some photos and a short description of some of the models.

 Khody, Addison and Nathan created models of different viruses. A virus needs a host cell to survive and multiply. They are parasites and up to ten times smaller than bacteria cells. This is part of the reason why they are transmitted so easily and can be airborne.
