Review the immune system with this video by Mr. Anderson (note the castle analogy!)

Watch the following videos from Khan Academy and take notes in preparation for a quiz on the immune system on Friday.
B Cells

APC and MHC

As requested by Mel: (So, motherhood calls, so will add some tomorrow in the early AM. This will get you through the first video. Just take good notes on the second video and you'll be okay!!!)
1) What is the relationship between the MHC, antigens and antibodies?
2) Describe the structure of an antibody. What do antibodies do? (This is at the end)
3) How can there be so many different variable groups on membrane bound antibodies, I mean HOW?!
4) What is clonal selection?
5) Contrast plasma cells and memory cells.
6) How does the B cell response explain why you don't get sick from the same virus twice?
Get ahead:
