Immune system, illustration
Illustration of a womans immune system and the immune reactions that halt progess and eliminate micro-organisms that can invade the organism. A micro-organism (orange cell) present in the organism meets white corpuscles (beige cell) such as macrophages or dendritic cells. The latter can either phagocytose the micro-organisms or destroy them : this is the innate respone; or fragment them and present them to lymphocyte T cells (pink cell). In this way the lymphocyte TCD4 cells, due to the cytokines, will activate the lymphocyte B cells (green cell) which will produce antibodies to destroy the micro-organism. Other lymphocyte TCD8 cells are capable of attacking infected cells by the micro-organism (blue cell in the process of being destroyed) and destroy it.
