Key Stage 4
Meaning
White Blood Cells are specialised animal cells which protect the body from pathogens.
About White Blood Cells
- White blood cells are produced in the bone marrow.
- White blood cells can weaken and kill pathogens including viruses, fungi, bacteria and protozoa.
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.
