CB5 Immune Response Flashcards
What is a non-specific immune response?
A response that is the same regardless of the type of pathogen that is involved.
What is an antigen?
A protein on the surface of the pathogen, specific to that pathogen.
What is an antibody?
A protien that binds onto the antigens on a specific pathogen
What cells produce antibodies?
Lymphocytes
What do antibodies do?
Antibodies bind to the pathogen so white blood cells can find and destroy it.
What is the function of a lymphocyte?
Produce antibodies
What is the function of a memory lymphocyte?
Remain dormant in the blood and will recognise that antigen and cause the boody to quicky produce the corresponding antibodies to destroy the pathogen.
How does a vaccine make you immune?
Gives the body a chance to produce memory lymphocytes for the pathogen so it can quickly attacked by the body
What is present in your blood if you are immune to a pathogen?
Memory lymphocytes (that can produce the complementary antibody to the pathogen’s antigen).
What is a secondary infection?
A second exposure to a pathogen that has previously infected an organism.
What are 2 differences between the primary and secondary response to a pathogen?
The secondary response is both faster and larger than the primary response.
What is a vaccine?
A substance containing antigens used to stimulate the production of antibodies and provide immunity to a pathogen.
