Question

How does the humoral immune response function?

Options

• Through direct destruction of pathogens by macrophages alone

• Through specific lymphocytes producing circulating antibodies that bind, neutralise, and eliminate foreign antigens

• Through the development of lymphocytes in primary lymphoid organs

• Through the filtration of blood by the spleen

Answer 1

The humoral immune response is driven by specific lymphocytes (B cells) that produce circulating antibodies. These antibodies bind to foreign antigens, neutralise them, and mark them for elimination by other immune cells, providing protection against pathogens in body fluids.
