How do white blood cells respond to infections?

The white blood cells detect the foreign antigens on the cells surface. They then rapidly produce antibodies which match the antigens and attach onto them. This allows other white blood cells to engulf the pathogen by causing the pathogens to clump together. The white blood cells then destroy the pathogen by phagocytosis. The antibodies then linger in the blood so they can be rapidly reproduced upon reinfection.
