Secondary level question-lymphocyte vs phagocyte

[lsc04361]

i am a secondary student and i confused about the difference between lymphocyte and phagocyte, as the textbook mention very little about it. Sorry for asking such simple question here...

I know that phagocyte is for the phagocytosis. But i dunno what lymphocyte responsible for except turning to a memory cell after the primary respond.

In conclusion, What is the relationship between lymphocyte and phagocyte, and What is the role of lymphocyte?

======
The second question is about the immune system(basic concept)
After the primary respond, some of the lymphocyte turns to a memory cell and recognize the pathogen.
When the second respond happen, are three of them-[phagocyte, lymphocyte, antibody]-will all produce in a large amount in a short time?

Finally, i want to ask that, is lymphocyte or phagocyte specialized for a pathogens? like antibody.

======
i have try to find the answer at wikipedia, but i dun quite understand the articles there.
thank you.
