Use your notes to make a flow chart demonstrating how different components of the immune system work together to destroy a pathogen with focus on adaptive immunity
Antigen enters the body
T Cells
Cytotoxic T Cells
Recognise body cells infected with an intracellular pathogen (e.g. a virus or bacterium) and then release chemicals that cause the infected cell to die. Cytotoxic T cells can also kill cancer cells and the foreign cells of a transplanted organ
Helper T Cells
They cannot destroy cells or antigens, but instead they are used to stimulate an immune response to antigens. Helper T cells are stimulated by antigen-presenting cells. The helper T cells then interact with other immune cells and produce chemicals to stimulate phagocytes, B cells and cytotoxic T cells
Memory T Cells
Memory T Cells remain in the body after the primary exposure to an antigen to allow a more effective secondary response, should re-exposure to the same antigen occur
Suppressor T Cells
Suppressor T Cells are immunosuppressors, meaning they inhibit the immune cells at the end of the immune response
