Thanks for the very detailed answer in that one - I kinda imagined the did a 'in/out connection' and basically filtered out the plasma and put the other stuff back in (possibly with some saline...???)

Also thanks to the other responses from everyone.
I might have one more question coming up - if i could continue the inquiry.....
And that's why I'm here eating HFLC Primal/Paleo.
