Today we are learning about the immune system.  Those who were absent need to look over the linked Power Point presentation.  There is a "fill in the blank" note sheet that is posted on our class web site.  Please click here for the notes.  If for some reason the link won't work, please go to our class website under the "resources" tab.  Then, click on Cell Biology and Disease.  The power point and link are near the bottom of the screen.
