Immunology

Immunology is the study of the structuree and function of the immune system which is responsible for the protection from invading foreign macromolecules or organisms. It is a broad branch of biomedical science that covers the study of all aspects of the immune system in organisms. It deals with the physiological functioning of the immune system in both healthy states and immunological disorders (autoimmune diseases, hypersensitivities, immune deficiency, transplant rejection); the physical, chemical and physiological characteristics of the components of the immune system in vitro, in situ, and in vivo.
