Cells and the Immune System: The Immune System

Understanding the immune system is crucial, including non-specific and specific bodily responses.
Key content: each cell type has specific identifying molecules on the surface including proteins.
The immune system uses these molecules to identify pathogens, cells from the same species, abnormal cells and toxins.
Understanding of antigen and antigen variability’s effect on disease and prevention is required.
Need knowledge of the process of phagocytosis of pathogens and the destruction of these pathogens by lysozymes.
Must know about T lymphocytes’ response to foreign antigens (cellular response).
Must understand the role of antigen-presenting cells in the cellular response and the role of helper T cells.
Knowledge about other T cells is not necessary.
Understanding the interactions and using key terminology such as antigen is important.
Suggestion to draw a flow diagram to conceptualise these stages.
