Watch the bacteria infect cells and the immune system fight them off. A summary of the next part. Tan cells are normal cells, green is bacteria, and red is the immune system. DISCLAIMER THIS IS NOT THE FULL IMMUNE SYSTEM The green squares are bacteria and when they touch the tan squares cells they can infect them, then the infected cells will begin to produce bacteria instead of more cells. The red squares are macrofages which will consume bacteria and the red squares with 4 poles sticking out are killer T cells which will kill infected cells also the red squares with 12 poles are B cells and produce antibodies which are the Y shaped things which will kill bacteria. However it takes time for the B cells to be activated . Most of the time the immune system wins but ocasionaly the bacteria kill all the cells. ENJOY!
