THE ROLE OF IMIMUNITY IN DISEASE PREVENTION
Keywords:
Immunity, antigen, antibody, T-lymphocyte, B-lymphocyte, cytokine, phagocytosis, vaccination, microbiota, immune responseAbstract
Immunity is a complex biological defense system that protects the human body against bacteria, viruses, fungi, and other pathogenic agents. This article analyzes the anatomical and functional basis of the immune system, the mechanisms of innate and adaptive immunity, cellular and humoral immune responses, and the role of immunity in the prevention of diseases. Based on modern immunological studies, the effects of vaccination, gut microbiota, vitamins, and lifestyle factors on immune function are discussed. The article highlights preventive strategies for infectious and chronic diseases through strengthening the immune system
