Chapter12 microbiology

3. – Immunization involving the transfer of antibodies for immediate but temporary effect.
4. – The region of an antigen receptor that differs greatly between cells and provides specificity.
6. – The process of inducing memory responses by introducing a pathogen or its parts into the body.
10. – Key white blood cell players of the adaptive immune system, including B and T cells.
12. – Rapid, non-specific host defenses like skin and phagocytic cells that act as a first line.
13. – Specific host defense that is slower to develop but provides long-term protection.
14. – Type of cell that "records" information to fight a pathogen if it returns.

1. – The immune response where antibodies defend against infection in body fluids.
2. – Type of B cell that actively secretes antibodies.
5. – Any substance that can elicit a response from a B or T cell.
7. – T cells that directly destroy virus-infected or cancerous cells.
8. – The organ where T cells go to mature after being produced in the bone marrow.
9. – The small, accessible part of an antigen that binds specifically to an antigen receptor.
11. – Known as the "conductors" of the immune system, these T cells activate other immune cells.
13. – A soluble form of the B cell receptor secreted into the blood or lymph.
