In brief: Cells,tissues,organs

The immune system is a network of cells, tissues, and organs that work together to defend the body against attacks.
Lymphoid organs (produce white blood cells that fight invading organisms) found throughout body, in bone marrow, thymus gland, lymph nodes, tonsils, appendix, lining of digestive tract and lungs.
