		<description>1. Wbcs recognize foreign invaders through receptors that recognize bacterial, viral ao fungal ligands.
2. Macrophages are involved in antigen processing and presentation to T cells.  Thay are also phagocytoc, and produce antiviral interferons.
3. T cells use the T cell reseptor, while B cells us surface IgM.
4. B cells are the only source of antibodies.</description>
