Your Immune System

Did something grow on the surface of the potatoes?

You will find that microbes will have grown on both potatoes, even the one peeled with your washed hands.

If washing does not get rid of the microbes why don't you get sick from the microbes on your own hands?

Your immune system is always on the lookout! Thorough washing does get rid of some of the microbes. Any small number of malicious (bad for us) microbes remaining will be dealt with by your body's immune system.

Did you know?

1. Some microbes in our bodies are actually beneficial (useful).

2. Occasionally the immune system works against us by attacking our own cells or foreign cells we want to preserve, like an organ transplant for example.
