The immune system consists of physical barriers as well as biochemical reactions. Physical barriers include skin, tears, saliva, mucous membranes of internal organ surfaces, filtering hairs, etc. Internal organ systems involved in providing immunity are the bone marrow, lymphatic system, spleen, thymus, appendix, white blood cells, parts of the digestive system, etc. Moreover, the endocrine system closely controls many immune responses.
