where are unit 2?

Can someone help with immunity!!!!!!

So i understand phagocytosis

And I know humoral immunity is when the pathogens have not yet entered the cell, and all the stuff with helper T cells activating them and causing mitosis to form plasma cells and memory cells.

But with cell mediated response, does it go back to the phagocyte/macrophage in phagocytosis that has the mhc proteins on its surface, the helper T cells bind to these mhc proteins with its complementary binding site, but then it says the T cells divide by mitosis (clonal expansion) into the t killer cells and whatever. But where does the B cell come in to this, like from the image I've got it just appear on the activated T cell from no where?
