Immunology is a broad branch of biomedicalscience that covers the study of all aspects of the immune system in all organisms. It deals with, among other things, the physiological functioning of the immune system in states of both health and disease; malfunctions of the immune system in immunological disorders (autoimmune diseases, hypersensitivities, immune deficiency, allograft rejection); the physical, chemical and physiological characteristics of the components of the immune system in vitro, in situ, and in vivo. Immunology has various applications in several disciplines of science, and as such is further divided.
Histological examination of the immune system
Even before the concept of immunity (from immunis, Latin for "exempt") was developed, numerous early physicians characterised organs that would later prove to be part of the immune system. The key organs of the immune system are thymus, spleen, bone marrow, lymph vessels, lymph nodes and secondary lymphatic tissues such as tonsils, adenoids, and skin. Two major organs, the thymus and spleen, are examined histologically only post-mortem during autopsy. However some lymph nodes and secondary lymphatic tissues can be surgically excised for examination while patients are still alive.
Many components of the immune system are actually cellular in nature and not associated with any specific organ but rather are embedded or circulating in various tissues located throughout the body.
