Digestion in space/0g

a reply to: TerryDon79

he intestines are a living thing. When visibly exposed during surgical operations, it seethes and undulates like a snake. the lining is squeezing the material within it, kneading it, digestion is a process like making dough by hand.

The gurgling and churning noises you hear is all that activity going on down there in your bowel basement…

Funnily enough, when a swanne posted about the stomach and the muscles etc I YouTubed a vid of stomach surgery then went from there. I never realised that that was what the stomach actually did.

Next time I have a stupid question I'll make sure to post it lol.

Good answers here. Also, due to surface tension, any liquid-like food mush will actually try to stick to the inner surface of the stomach and intestines, even if there are some voids in the middle.

Astronauts experienced this surface tension phenomenon with urine in their bladder - instead of collecting at the bottom of the bladder (and thus triggering the need to pee when there was enough of it), their urine sticks around the walls of the bladder, accumulating to the point the bladder is almost completely full and they need to pee really really bad.

We are just meat tubes surrounded by mechanisms to get energy to the edges and back!

You also could ask, "How can anybody breath in zero G" and get pretty much the same answer (as long as the vehicle is pressurized your normal muscles do their thang). And as far as expelling things... well there is a special vacuum for that!

About the only real difference in zero G is staying hydrated (I think you need a little more water) for some reason that escapes me now.
