good question actually, the esophagus can squeeze things towards the stomach without gravity’s help.

I don’t know about you guys, but I just open my throat straight down to my stomach and pour the food in.

This was legitimately a significant concern that early space programs had. Like, how well would people be able to swallow in free fall, would certain kinds of food cause problems? The food experiments during the Gemini program are pretty interesting

Swallowing is mechanical action; that’s how astronauts can eat and how you can eat or drink upside down if you were really wanting to.

Saw someone drinking a whole beer from a funnel while being being held upside down. People do this and I basically die when drinking a sip of water while lying in bed.

Ever heard of a kegstand?
FooBarrington@lemmy.world 10 hours ago
Maybe the issue is that you’re too horizontal? Try doing a handstand first.

Can you swallow things when you’re laying flat? I imagine swallowing food in space would be no more difficult.
exasperation@lemmy.dbzer0.com 3 hours ago
You can swallow things while dangling upside down. The esophagus is strong enough to work against gravity.
But liquids are a little bit more difficult, because they tend to flow in unexpected places in the mouth/sinuses/nose before trying to swallow.

Once I had to drink barium while being tilted upside down on a big table while they watched it with X-rays… apparently that’s a medical test lol I didn’t find it anymore difficult than drinking normally personally but it has to do with the strength of your swallow most of all, which is what they were testing at the time.

What if you’re upside down?
roscoe@lemmy.dbzer0.com 3 hours ago
Yup, cures my hiccups. Lay back over something so mouth to stomach is reverse inclined, as close to vertical as I can get. Then take several swallows of water. Either one mouthful that I took before I laid back swallowed a little at a time, or several sips from a straw after laying back.

I think there was a science experiments book for kids that dared me to drink water upside down through a straw while hanging from monkey bars or something. It was meant to show how our body deliberately moves food towards the stomach instead of solely relying on gravity, but instead it showed that I my legs were too weak.
A shame these experiments are deemed to dangerous nowadays and people have to show their ignorance online, simply because the new metal straws have pierced the brains of anyone who did them.

I am confused by this, straws go in the mouth, if people are sticking them in their brains, they’re doing it wrong, or are you saying there is a crack team of assasins out there who’ve vowed to keep this knowledge secret in a particularly gruesome manner?
Tudsamfa@lemmy.world 7 hours ago
I implied that I fell from the monkey bars, and since I was drinking through a straw, I fell head first onto my water glass with the straw in my mouth that was below me. A common misconception of metal straws is that they are dangerous and can pierce through the mouth into the brain.
I guess I could specify where the glass is in the experiment.

I mean I can totally see kids choking on water while doing this too. Yes muscles but I am sure gravity helps too.

Cause we have lots of places to do science with gravity, its nice to have a place to do science without it.
And hard to maintain the force without damaging the ship. We have small space stations and shuttles and they would need to rotate really fast to generate gravity similar to earth and that is taxing on the structure and you since your feet would have a lot more gravity than your head closer to the center of the circle.If you have seen project hail Mary that is why there is an extendable counter weight actually. It helps move the central point of the rotation further away from the astronaut and let’s it rotate slower and have more consistent force.

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?
tigeruppercut@lemmy.zip 6 hours ago
Most water back in the day was at ground level, so if we could only rely on gravity we’d have had a hell of a time bending down to slurp it up.
MonkderVierte@lemmy.zip 5 hours ago

JayleneSlide@lemmy.world 7 hours ago
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.
Zron@lemmy.world 7 hours ago
How about the fact that being a qaudruped is basically the body plan for mammals. Humans are the weird ones for standing upright and having our mouths be directly above our stomachs. Every other mammal has their stomach mostly parallel with the mouth while standing. In order for food to get to the stomach, you’d need some force moving the food sideways towards the stomach.

Probably also helps with eating while lying down.

bdonvr@thelemmy.club 12 hours ago
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.
Most of your body processes are in a small enough space that capillary action overtakes gravity.

So what you’re saying is they should alternate between upside down and right side up
ajmaxwell@lemmy.world 13 hours ago
There’s a slight increase in the blood pressure in your upper body, and a small possibility of thrombosis, blood clots forming in your veins. But after 50+ years of space flight no one has had complications.

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.
