Sample Flashcards

What is an antigen?
A foreign substance that triggers an immune response by being recognized as non-self by the immune system.
What is an antibody?
A Y-shaped protein (immunoglobulin) produced by plasma cells that binds specifically to antigens to neutralize or mark them for destruction.
