A Level Biology Revision "Antigens and Antibodies"

You can find all my A Level Biology videos fully indexed at www.freescienc...
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.

@@Freesciencelessons thank you very much, I was struggling with this topic. Will you do A2 videos next year?

[@ShimmerRain6]

what's the difference between antiBODIES and antiGENS

[@Freesciencelessons]

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.
