Create a flow chart showing how the following events fit together in a normal immune reaction:

-Memory B cells
-Cytotoxic T cells
-Epitope attached to MHCII protein on macrophage membrane
-Macrophage ingests antigen
-Produce antibodies
-B cells divide
-Sensitized T cells divide
-Activate complement
-Destroy the antigen
-Stimulate B cells with the same antigen receptor
-Antigen digested
-Helper T cells
-Attach to antigen to form immune complexes
-Plasma cells
-Help phagocytic cells find antigen
-Macrophage presents antigen to T cells
-T cells whose receptors match the antigen are sensitized
-Destroy cells infected with the antigen
