The Immune System: T cells & B cells | A-Level Biology Revision | AQA
Показать описание
This tutorial covers the humoral response and antibodies. This video will help you understand the difference between the roles of B cells (B memory and B effector cells) and T cells (T helper, T killer and T memory cells) in the body’s immune response.
The T-cells are activated by the antigen-presenting cells which in turn activate T-Helper Cells which activate the Cytotoxic T-Cells and B Cells. The Cytotoxic cells will kill the pathogens - this is part of the cellular response. This tutorial is for AQA and Edexcel Students. OCR Students this covers some of your basic content however you go into more depth. Check out the "OCR A Level Biology (AS)" Playlist.
