A level Biology: Immunity Overview Diagram

A clear visual overview of the immune system, covering the roles of phagocytes, antigen presenting cells, T-helper cells, T-cytotoxic cells, plasma cells and memory cells. The diagram shows the sequence after infection with a new pathogen, which leads to clonal selection of B cells, production of antibodies by plasma cells, and agglutination. Finally, the diagram shows how agglutination leads to phagocytosis of clusters of pathogens which bear the foreign antigen.

This would be an excellent aid for revision of this area, alternatively, it could be given to students at the start of the topic to help orientate them as they learn about each interaction in sequence (note this resource is also available as part of the second lesson bundle for the combined cost of £3).

Students often struggle to recall the complex interactions between the cells in the immune system and I was unable to find a resource which gave a clear visual overview. I took my time and created this resource which has served my students well over the years since I created it. Sections can also be transfered to powerpoint presentations conveniently using the snipping tool to either facilitate creating further revision resources, or adapt resources you may have.
