let us define the premise first, so we have solid ground to stand on. What is the immune system, what is the context it works in, and what are the tiny parts that do the actual work? After we have covered these basics we will explore what happens if you hurt yourself and how your immune system rushes in to defend you. Then we’ll explore your most vulnerable parts and see how your body scrambles to protect from a serious infection. And lastly, we’ll take a look at different immune disorders like allergies and autoimmune disease and discuss how you can boost your immune system.
