The Immune System

Our immune system is the first line of defence against bacteria and viruses that are eager to cause diseases and infections in our bodies. Is a cold virus in the air? Has a nasty germ entered your body? Did you touch something dirty and full of bacteria? Your immune system is on the job to protect you!

Our immune system is quite complex and sophisticated, but guess what? It is the most effective army in the world!

The video below shows the system in action against invading bacteria. Watch it and be amazed!
