A white blood cell is a specialised cell which is used to fight infection.

White blood cells have a large nucleus to make antibodies to fight infection.

White blood cells are part of the immune system.

White blood cells are specially adapted to fight infection.

White blood cells make up less than 1% of the blood.

White blood cells are produced in the bone marrow.

White blood cells can weaken and kill pathogens including viruses, fungi, bacteria and protists.

There are two main types of white blood cell that you should know:

Phagocytes - Which engulf and then break down pathogens.
Lymphocytes - Which produce antibodies which attach themselves to pathogens to make it easier for the phagocytes to engulf them and produce antitoxins to cancel out the effects of toxic chemicals made by the pathogens.
