The don't make into your cells and tissues, because they're not digestible.
Anything bigger than a "small molecule" doesn't make it through the membranes into your bloodstream. Even individual proteins are too big, let alone a chunk of your frying pan big enough to see.
When talking about a small polymer, I was mainly commenting on microscopic flakes and lakes laced with "chemically inert" molecules that have devastating physiological effects.
Either way, what you claim is simply not true by any reasoning [1], though I do agree eating teflon flakes in moderate amounts should not pose much concern.
