About 25% of the white blood cells are LYMPHOCYTES They are part of the body’s immune system and produce soluble proteins called antibodies. Antibodies can recognise particular types of pathogen ANTIBODIES attach to ANTIGENS Antigens are substances found on the surface of cells, including bacteria and pathogens Different antibodies attach to different antigens. Meaning the body’s immune system can’t recognise foreign antigens (antigens that aren’t normally produced by the body but by pathogens Antibodies can neutralise toxins produced by pathogens. They can cause the destruction of pathogens by- Causing bacteria to burst open and die Labelling the pathogen so that it is recognised more easily by phagocytes Sticking pathogens together so they can be engulfed by phagocytes more easily
