The problem is that things like microplastics cannot be removed easily. (This is called bioaccumulation.) But if you bleed and lose some blood, the new blood will take time to accumulate.
The blood supplies to and through every single organ the vast majority of which are much more likely to catch and accumulate particles than the stream or vessels themselves.
Blood doesn’t work like that, as it is constantly moving and being replaced. It is not a bucket.

If it flows out when the blood moves then it wouldn’t accumulate there in the first place. I’m not sure what you’re having difficulty with here.
It doesn’t flow out when the blood moves, because the bloodstream is a closed loop (more or less). It can only flow out if you lose blood.

That’s true.
