It only stops solids above a certain size, so a filter is more accurate. Check valves generally stop everything or all of a class of things, the turtle passes all liquid and some solids

Our heart valves are check valves

A class of things = large solid objects like jellyfish and food?

Maybe, I'm no linguist or expert. Small jellyfish will go out with the water

I mean you're right. The idea is filtration by size exclusion but only in one direction.
