So first, I'm going to assume that you're doing GCSE Biology, in which case lymphocytes are a type of white-blood cell, and the other type that you learn are called phagocytes - to be explained later.

Lymphocytes basically bind to the antigens of pathogens. Think of it as uniquely shaped protrusions on the cell membrane of bacteria, and different pathogens have differently-shaped antigens. So the lymphocytes then produce things called antibodies, which basically stick to the surface of the pathogen, and act as a flag for the phagocytes to identify the pathogen.

Phagocytes search out the pathogens, and then engulf them, before digesting it with enzymes. Pretty simple.

Another point - memory lymphocytes also retain their memories of the pathogen so they can identify it when it invades the body again - it's why your body becomes resistant to diseases you have caught before. They also produce antitoxins to negate any toxins the pathogen might produce.

That's about it, hope it helps.
