1950s Video of Immune System in Action

[youtube]http://www.youtube.com/watch?v=I_xh-bkiv_c[/youtube] Great video of a Neutrophil cell, a type of immune cell, relentlessly chasing down a bacterium while pushing aside red blood cells. I found it fascinating to see our immune system in action. The video was apparently taken from a 16-mm movie made in the 1950s by the late David Rogers at Vanderbilt University.
