Primary and secondary immune response?

Question

what is the difference between primary immune response and secoundary immune response? Include a drawing or graph to illustrate?

Answer 1

primary immune response refers to the first encounter of your immune system with a virus or bacteria.  when this happens, naive T cells and B cells are activated and form memory cells.  This process takes a week or so, which allows you to get sick and not feel well, but these cells eventually clear the pathogen from your body.

a secondary immune response refers to a re-encounter of the same virus/bacteria against which you have memory T cells and B cells.  since the memory cells have seen the bug before, they can respond very rapdily and robustly, preventing you from feeling sick.  

vaccines artificially mimic a virus/bacteria/parasite to generate a primary immune response without making you sick, so that you can generate a rapid secondary immune response to the bug the first time you get it.

go check the bio the book page 614-615 (diagram on page 614)

Answer 3

First Line of Defense (Primary)- Skin and Mucus Membranes

         The skin is covered in good bacteria, staph e. that fights off staph o.

         Mucus catches small particles of bacteria.

         Skin and Mucus secrete oil and sweat to get rid of bacteria.

Second Line of Defense (Secondary)-

         Phaygocytic White Blood Cells

         Antimicrobial Proteins-  Endorphins (provide a natural high) - Interferon (acts as a cure all) - Lyzymes (enzymes in lysosomes)

        The Inflammatory Response- Signal is sent around the body, hisamine is released when injured, foreign proteins invade

sorry that I don't have any picture, they are all in my biology notebook

Hope I could help to the best extent that my notebook has!
