    Hi there - we appreciate that the “just filtered” part of our title has drawn a few comments and we want to address it. First off - you’re right; you could say lots of things are filtered blood products, including urine and even the carbon dioxide we breathe out. We decided to make this video because we believe most people, including ourselves, don’t think about how the same thing is true for a substance a lot of us drink every day - milk from an animal - and that communicating that fact would lead folks to a different appreciation of what milk is. Secondly - you’re also right; we didn’t fully convey the amazing things that the mammary gland does. Almost all of the precursors to the stuff in milk DO come from the bloodstream, but the special cells in the mammary gland transform many of them into their final milky forms, which we simplified in the video as “do some chemistry on them” and in the title as “filtered.”

    I cant decide what sounds dumber you thinking that filtering is chemistry or attempts to simplify something as obvious as this.
    The hair on your head must have more cells in it than the contents of your skull.
    was this an attempt to gross people out?`
    or was it an attempt to spread misinformation?
    As a person whose culture often adds pig blood to various dishes it only disgusted me of what kind of person you are.

      Blood is just water with various nutritions and minerals. but you can try filter the blood it wont do anything it will remain blood. however if you had a brain in that lil head of yours you should know that you must use the process of distillation to separate the two Your nails for example can be considered hardened blood if people where to use your retarded simplifying methods of spreading misinformation.
