Question

Quizplus · Accepted Answer

IgG is a type of antibody that is responsible for providing long-term immunity to infectious diseases. Once the body is exposed to a pathogen, IgG antibodies are produced and remain in the body for a long time, providing protection against future infections. Plasma cells produce antibodies, including IgG, but the production of plasma cells is not specific to long-term immunity. IgE and mast cells are involved in immediate hypersensitivity reactions, not long-term immunity.
