Immunology is a branch of medicine that covers the study of immune systems and management of its disorders. Malfunctions of the immune system and immunological disorders include autoimmune diseases, hypersensitivities and allergies, immune deficiency, and transplant rejection.
Immunology overlaps numerous other fields of medicine. It is the immune system that underlies the value of vaccination, also called immunisation. The important lymphoid organs of the immune system are the thymus, bone marrow, and lymphatic tissues such as spleen, tonsils, lymph vessels, lymph nodes, adenoids, and liver. Many components of the immune system are cellular and circulate throughout the body.
Immunologists are core to investigating and managing allergy disorders, identifying allergens and potentially achieving desensitisation.
