- You can find all my A Level Biology videos fully indexed at www.freesciencelessons.co.uk/...
In this video, we look at antigens and antibodies. First we explore what is meant by the specific immune system. We then explore the features of antigens and the difference between "self" antigens and foreign or "non-self" antigens. Finally, we look at the structure of antibodies and the roles of antibodies including agglutination.

Thank you for the wonderful, informative video
God bless, I was waiting for this video
You saved my olevel grades and now you’re saving my alevel grades
Do you still do GCSE work? If so, can you make a video on the Limitations of the Particle Model?
its quite simple tho
You said 4 functions but you only mentioned 3?
Will you upload the rest of the immune system videos soon? Please do.
I've just uploaded the next one.
@@Freesciencelessons thank you very much, I was struggling with this topic. Will you do A2 videos next year?
Yes I'll be starting the A2 content in the next couple of months.
Will you make workbooks for A level?
Yes I do plan to but I still have a lot of A level videos to make before then.
I love your vidos
Epik
what's the difference between antiBODIES and antiGENS
Antigens are identified by the body as foreign eg viruses, bacteria etc. Antibodies are proteins made by B cells. Antibodies stick to specific antigens. This targets the antigen for destruction.
