Veins are small so capillary action keeps things in order.
With no gravity though you'll have higher blood pressure to your head (and less to the legs)- it kinda makes astronauts faces a bit puffy. iirc this can slightly negatively affect vision long term.
Most of your body processes are in a small enough space that capillary action overtakes gravity.

Given how filthy the ISS is, I don't know if I'd want to eat anything not nuked into oblivion.
Why would it be filthy? It's not like they get a lot of dirt out there
Dust comes from human skin flakes.
Part of it yes, but I'd assume they also clean there sometimes.
Part of it is I don't know how skin particles will act inside a space station. Are there static electricity forces that would make it stick to surfaces, or does it remain suspended in air until the filtration gets to it?
Static electricity would definitely be a factor, but there’s probably pretty good air circulation and filtering. That combined with regular wipe downs of surfaces probably keeps dust under control.
I know the moon missions in the past had a hell of a time dealing with lunar dust. It’s super fine and static was sticking it to everything.
Imagine trying to clean it. You can't whip out a mop. Showers, wash cycles etc are all no go. Not too mention experiments from plants, chemicals, drugs etc which create their own issues. In some ways it's clean, but others not so much.
You can use a vacuum cleaner, but since there's hardly any gravity most would already get picked up be a simple air filter.
"bread"
Right, why do we have that redundant swallowing mechanism? ~~Did enough people choke while eating upside down to make a difference? Wait, this is from our ape-y ancestry?~~
My guess it's even older than that. My bullshitspiration is that peristalsis enabled more complex digestion when our quadruped ancestors needed more nutrition options.

Probably also helps with eating while lying down.
