What is the main function of acquired immunity?

The main function of acquired immunity is to provide a specific and adaptive response to pathogens that the body has previously encountered. It involves the activation of lymphocytes, such as T cells and B cells, which recognize specific antigens and generate a targeted immune response. This type of immunity also includes the development of immunological memory, allowing the body to respond more rapidly and effectively to subsequent exposures to the same pathogen. Overall, acquired immunity enhances the body's ability to fight infections and provides long-lasting protection.
