Cells and the Immune System: The Immune System
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.
