It's a problem 12 wants us to give examples and talk about specificity, diversity, and memory, and how they aid the immune system.
00:24
So an example of specificity would be when an antigen is presented, antitotoxic cells kill that cell.
00:52
But only that cell.
00:53
They don't kill everything.
00:54
And what that's important is so when your immune system comes in as your defense, it doesn't destroy healthy cells.
01:01
It only destroys the unhealthy cells.
01:04
Why diversity, an example of diversity, so good, so healthy cells, day, safe.

On the flip side, diversity would be something like a macrophage, which just sucks up anything that looks suss, right, anything that shouldn't be there...
