Growing up I was friends with this boy name Chris, one day Chris wasn't feeling so well and soon to have found out that he had foreign invader, antigen. His parent took him to the doctors to get it checked up, the doctor told him that his immune system fought it off.

The following was Chris's defense:

1. Non-specific defense
2. Specific defense
3. Skin
4. Nose hair
5. Mucus
6. Inflammation
7. B-cells
8. Antibodies
9. T-cells
10. Phagocytes.

Non-specific Defense:

Non-specific defense job is to block invaders and fight off invaders. Since non-specific is good it is the first line of defense.

Specific Defense:

The specific defense is the immune system and it attacks these invaders once they enter the body.

Skin:

The skin is the outer layer to prevent invaders from entering the body. The skin is what helps block invaders from entering the body.

Nose Hair:

Nose hair traps dust which prevent invaders from entering into the body. They force invaders out of the body, invaders are stopped by the nose hair.
