The Immune System
This system is very important to our body as it helps fight lots and lots of germs everyday. It protects our body from other wrong substances, and is just like other body systems, made up of the same contents: Cells, Tissue, Organs, and special proteins that can benefit the body on keeping out germs. The immune system protects you from being ill and getting an infection through a process called immune response. This process kills and removes all disease-causing bacteria from the body. If our immune system went bad, our body would be constantly sick and would not be able to handle things.
