I was looking for a show I watched when I was a kid (90's). I don't know what it was called. It was about how the body worked. The granddad red bloodcel told it to his grand children, and all the cells were in human form, if that makes sense The one who fought the viruses were in like spaceships.
I don't know much more. Does anyone reginese this show?

Sounds like Once Upon a Time... Life (http://en.wikipedia.org/wiki/Once_Upon_a_Time..._Life)
