Inside your body, designated cells and specialized proteins work together to form your immune system, defending you against infection. The immune system is located all over the body in order to provide quick immune responses wherever infection occurs. The immune cells travel through blood and lymphatic system vessels. Our immune system has primary immune response as well as secondary response. To enable communication between immune cells, there are special structures within the lymph nodes and the spleen.
