Immunology is a branch of medical and biological sciences that studies the immune system. It is concerned with the physiological functioning of the immune system, including health and disease, as well as the malfunctions of the immune system. The immune system is capable of distinguishing between self and non-self substances. An antigen is a material that activates the immune system by triggering lymphocytes. The immune system responds by secreting the antibodies which are proteins to neutralize the disease causing micro-organisms and thus protects us from being sick.
