This is where our filtrate is right here.

The glomerular filtrate is coming in this direction.

And so we end up having filtrate in it.

Filtrate is just the stuff that gets squeezed out.

Instead, a positive hydrostatic pressure drives water and solutes across the filter membrane from the blood compartment to the filtrate compartment, from which it is drained.
