Immunology is study of the immune system in all the living organisms on earth. It is an elaborative branch of biomedical science. The specified objective as dealt by Immunology is the physiological functioning of the immune system in the living beings. It is related in every possible state in states of health and disease. Immunological disorders are like those of immune deficiency, autoimmune diseases, hypersensitivities and transplant rejection. All these disorders are due to the malfunctions of the immune system in the living body. Under the basic rules the components of the immune system are all cellular in nature. It is wrong to think that they are in any way associated with the particular organ. On the other hand the capacitance embedded or keeps in a circulating motion in various tissues located throughout the body of the living being.

ORIGIN
The word immunity has originated from the Latin word, immunis, meaning “exempt”. The functioning of immunity in the body is directly related to the key primary lymphoid organs of the immune system. These are all represented by the terms known as thymus, bone marrow, lymph nodes, spleen, lymph vessels, adenoids, skin and tonsils.

APPLICATION

In order to cure a disease or in other words to correct the immunizing effect of the body there is the application of a system or procedure called immunotherapy. By means of radiation in radio therapy and drugs through chemotherapy the process of immunotherapy is very effective while treating the cancer patients. The objective is to make the body strong enough to fight with developing cancer cells. There is one more application of immunotherapy, is the immunosuppressed that is applicable while treating HIV patients and autoimmune diseases.
The actual use of immunology is to comprehend the actual bond between antibody and antigen in the living being. It works as a catalyst in making the body get rid of the disease. Its usability is highly acclaimed in the detection of substances in a variety of diagnostic techniques that has been developed by the modern scientific inventions. After making the detection of the antibodies in the body the desired antigen gets conjugated with a fluorescent label, color-forming enzyme or radiolabel.

Thus the speculative aspects show that the immunology is all about the chemical, physical and physiological components of the immune system. It is all related to the process of increasing the capacity of the body in fighting against the unwanted ingredients in the body. It has got various applications in several disciplines of medical science and in safeguarding from life threatening diseases.
