The immune system is a complex collection of organs, cells and tissues that work collectively to protect the body against disease caused mostly by pathogens (bacteria, viruses, parasites and fungi).

Parts of the immune system include the tonsils, lymph nodes, appendix, spleen, thymus, skin and mucous membranes.

The lymph nodes in particular produce lymphocyte cells (white blood cells) whose role is to destroy invading pathogens.

Eleven claims have been authorised by the EU for contributions to the normal function of the immune system, and these are:-
