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!!

I know, ELI5, but there are entire college classes on this.
Basic pathway for water: mouth, esophagus, absorbed in digestive system (lots in colon), fluid goes to the blood, kidneys filter blood with salts and junk and a lot of water, then through the ureter to bladder them through the urethra and out.
Nutrients are largely broken down and absorbed in the digestive tract, but some pass through without being absorbed.
Feces is a lot of plant material and fiber and water and junk that couldn’t be absorbed. Some nutrients too, and bacteria.
