The resistance of organisms against infection is studied

The resistance of organisms against infection is studied in [B] Immunology. Immunology is the branch of science focused on understanding the immune system’s response to pathogens, including bacteria, viruses, and parasites. Immunologists investigate how the immune system recognizes and eliminates foreign invaders while maintaining tolerance to self. They study various components of the immune system, such as antibodies, T cells, and cytokines, as well as immunological processes like inflammation and immune memory.
By uncovering the mechanisms underlying immune responses, immunologists develop vaccines, therapeutics, and diagnostic tools to combat infectious diseases and disorders related to immune dysfunction. Immunology also plays a vital role in organ transplantation, autoimmune diseases, and cancer immunotherapy. Overall, the field of immunology is crucial for advancing our understanding of host-pathogen interactions and developing strategies to enhance immunity and combat infectious threats.
