: '''White blood cells''' make up less than 1% of the [[blood]].

: '''White blood cells''' can weaken and kill [[pathogen]]s including [[virus]]es, [[Pathogenic Fungus|fungi]], [[Pathogenic Bacteria|bacteria]] and [[Pathogenic Protist|protists]].
There are two main types of '''white blood cell''' that you should know:
*[[Phagocyte]]s - Which engulf and then break down [[pathogen]]s.
*[[Lymphocyte]]s - Which produce [[Antibody|antibodies]] which attach themselves to [[pathogen]]s to make it easier for the [[phagocyte]]s to engulf them and produce [[antitoxin]]s to cancel out the effects of [[toxic]] [[chemical]]s made by the [[pathogen]]s.
