There was once a big bad antigen, which is a bad germ that wants to enter the body. The body didn't fear, the immune system was going to save the day!

The body first talked to its skin, nose hair, and mucus ordering them to trap the big bad antigen and his gang and banish them from the body. This is the body's non-specific defense because they aren't going to target the germs.

The big bad antigen made its way past the first line of defense. The body needed a better plan. The body called in its phagocytes, T-cells, and B-cells to help save the day!
