Might seem like a silly question, but I’m not sure of the specifics on how a drink goes from your throat to your bladder.
Doesn’t the liquid go to your stomach along with the food you eat? Does it get evaporated by the acid or something? Does it go from your esophagus to your stomach to your intestines then bladder?
Or is urine not even partially the liquid we drink, but the end result of whatever liquids your body produced/was left with after digesting your drink, like how shit is what’s left and stored in the rectum (anus?) before expulsions?
This is just something that the specifics of which have been bothering me for over a handful of months lol. Would definitely appreciate an answer, but also semi-interested in a little more detail too if anyone would like to indulge that.
Thank you!!

To ELI5: it’s a big roller coaster ride, more or less. The coaster leaves the station (the glass) into a dark cavern (your mouth) and then plunging straight down that first thrill hill called your esophagus.
The riders get a moment’s rest as they swirl around another cavern called the stomach. Soon, though, the ride continues down the next hill, the duodenum, toward the crazy twisty back and forth section of the small intestines.
Along this bit of track, the passengers (water) get sent off into a bunch of side tracks as they pass into the bloodstream. It’s like every car in the coaster splits off in a different direction!
The heart pumps – I can hear it making that clankety-clank sound – as it pulls the coaster cars as far as the top of the head before they scream back down under the force of gravity.
The tracks rejoin and the coaster comes back together as a pair of trains as the blood is filtered into the kidneys through the renal arteries.
The coaster makes a jarring turn as the liquid gets ripped out of the bloodstream and into the beginning of the ending thrills: the ureters.
Zooming out of the ureters the coaster gives the riders one last sense of false security with a pause in the last big room of the dark ride, the bladder. Just as the coaster comes back together in one train again, the ride ends with a bang as the liquids come flying out the urethra to end the ride.
You get flushed down the toilet in the end, but at least the lines to get in the ride aren’t that long. Maybe it’s more like the log flume…
