- Description: This clip begins with Robert Winston explaining that our immune system can be likened to piranhas in the way it attacks foreign cells. He goes on to say that there are approximately 50 billion white blood cells in our bodies and that one of their functions is to engulf foreign cells. In vitro video footage of white blood and red blood cells is shown, as is the action of white blood cells engulfing bacteria. With thanks to "David Barlow Photography"

Ideas for use in class
- This clip could be used to explain how white blood cells act as a defence against invading micro-organisms. This clip opens with a question - What cells in our body fight diseases and how do they do this? It therefore lends itself very nicely to reviewing this question at the end.
