Question | Answer |
---|---|
anaphylaxis | Exaggerated,life-threatening hypersitivity reaction to a previously encountered antigen. |
antibody | Proteins that are the most inportant weapon of the immune system. |
antigen | Substance that is recognized as harmful to the host and stimulates the formation of antibodies. |
