Microbiology

We've covered some of the section on microbiology, here is what you should be comfrotable with by now:

• Bacteria and viruses exist EVERYWHERE. Everywhere. Everywhere.
• Some are beneficial to us, while other are pathogens and can cause disease.
• Our bodies have four different ways of defending against microbes (and white blood cells if those fail).
• There are also 4 main ways that bacteria can enter the body.

We'll cover vaccines and immunity next week, and then revise before a quiz before halfterm to make sure we're all ok with what we've done so far.
