IMMUNOLOGY

Detailed explanation-1: -A unique function of antibody is to initiate the clearance of pathogens via complement activation and binding to erythrocyte complement receptor 1 (CR1); the result of such binding sequesters the pathogen from invading susceptible tissue and may facilitate the destruction of the organisms by tissue macrophages (112).

Detailed explanation-2: -Antibodies attach to a specific antigen and make it easier for the immune cells to destroy the antigen. T lymphocytes attack antigens directly and help control the immune response. They also release chemicals, known as cytokines, which control the entire immune response.
