Hey everyone! I have an upcoming AOS2 SAC2 for Unit3 on immunity and all the signalling stuff. I still don't really understand it all, for example, naive and regular cells? Lymphatic system and MHC proteins? I was just wondering i someone would be able to explain those things to me? and if possible give me a guideline/checklist on what to look out for/study more of for the SAC (I know it's on the study design).
The content can sometimes differ between schools depending on how fast they cover the content and when they cover it. However, the general things I think it would be good to learn would be.
- What is an antigen?
- What is a self-antigen, non-self antigens?
- How do allergens elicit an immune response?
- What are some chemical and physical barriers? (i.e the 1st line of defence).
- Types of cells involved in the innate immune system + the complement system
- lymphatic system
- lymphocytes (B and T cells)
- How are these lymphocytes activated, what are they activated by, what is there functions etc
- Distinguish between humoral and cell-mediated immunity
- What are the two main T cells and their functions
- How to acquire immunity (passive/active), have examples
- DIffer between natural/artificial immunity
-Vaccinations/herd immunity
-Clinical use of mAb
Definitely not everything but going through this should be a good revision of an overview of the immune system in terms of what VCAA want you to know.
