Video at a Glance
- Adaptive immunity is a branch of the immune system that recognizes specific antigens.
- Adaptive immunity focuses on antibodies.
- It is called adaptive because when we are born, our bodies produce specific antibodies, and each one can only respond to a single antigen.
- Most antigens are never activated during a lifetime.
- Once activated, specific antibodies begin dividing to make more to fight the infection.
- Essentially, the immune system is adapting to make the needed T and B cells.
- The lymph nodes are designed to make sure that antigens come in contact with the correct antibodies.
