I am the Head of A-Level Biology at Birmingham Tuition Centre
I have put together revision notes for A-Level Biology
In this thread are the notes for AQA Unit 1 - I have another thread for OCR Unit 1
The Unit 4 notes for both will be uploaded later this week (Unit 2 and Unit 5 will be uploaded later in the term)
I hope you find the notes useful

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?
Also what's the difference of the memory cells that form from humoral immunity to the memory B cells that form with cell mediated? Am v confused 😥
