NPB 101 FINAL EXAM QUESTIONS & ANSWERS
What are leukocytes? - answers -aka white blood cells
- umbrella term for all immune cells
What two categories of leukocytes? - answers -lymphoid cells and myeloid cells
What consists of myeloid cells? - answers -monocytes/macrophages
Granulocytes
And precursors for rbc and platelets
Where do t cells come from - answers -thymus
Why do b cells come from - answers -bursa of fabricus
And bone marrow
What is necessary for cell mediated immunity? And what is cell mediated immunity? -
answers -t cells are needed
- an immune response that does not involve antibodies.
Cell-mediated immunity is the activation of phagocytes, macrophages, nk cells, antigen-
specific cytotoxic t-lymphocytes, and the release of various cytokines in response to an
antigen.
What is necessary for humoral immunity? And what is humoral immunity? - answers -b
cells
- antibody-mediated immunity
- helper t cells help these b cells differentiate into plasma b cells and memory b cells
Humoral immunity is adaptive immunity manifested by the production of antibodies by b
lymphocytes.
What are b cell receptors also known as? - answers -antibody molecules!
What do macrophages/monocytes do? - answers -the travel through tissues to dispose
of pathogens and clean up dead cells and other debris
True or false
Acquired immunity needs an innate response in order to work - answers -true
Difference between helper t cells and cytotoxic t cells - answers -helper t cells help b
cells mount humoral reponse while cytocoxic t cells go out and kill pathogens
themselves
What cells express mhc class 1? - answers -all cells
