I don’t know how to **properly** search this up on Google (i know how to type into the search bar and press enter and all that) so the answers I’ve been getting are about stomach acid dilution. My question is how does what we drink end up in our bladders if it goes into our stomachs first? Like, does stomach acid come into the mix and if not, how does our body know not to put stomach acid in our bladders? What path does it follow once it enters the stomach? I only know of the solids exit. How is the water separated from the acid if it is? If you drank enough would you just have an increased amount of acid? I don’t know anything about drinking except it goes into our stomachs, and somehow exits the bladder somewhere between clear or dark yellow depending on how healthy you’ve been with your choices of beverages.
Edit: clarification
In: Biology
It would be completely useless if everything we drank just ended up in our bladder. The trip from swallowing a liquid to peeing a liquid is not even necessarily a direct connection. That is you’re not necessarily peeing out the same liquid you drank.
So you’re basically a donut. There’s a single tube that starts at your mouth and goes all the way out your anus. The purpose of this tube is to smear food along its interior so that that food can be absorbed by your body. On the way it is chemically changed by acid, then changed by bile which is the opposite of acid, then reacted with a whole bunch of chemicals produced by your liver and pancreas. Finally special cells on the inside of the lining of your intestine basically pumps the valuable bits of what you ate and drank from the tube into your bloodstream .
Now one of the weird things that you have to consider is that plants take water and carbon dioxide and turn it into sugar and oxygen.
Your body takes sugar and oxygen and turns it into carbon dioxide and water .
At a chemical level sugars are basically tiny chemical batteries. Well actually they’re tiny chemical springs, but the battery is a more useful thing when talking about energy at this level of simplicity.
In the process of absorbing things, building things, tearing things apart, and all the other stuff your body has to do it produces waste products. Those waste products would be poisonous if they were allowed to build up in your system.
So your kidneys and your liver extract these toxins from your bloodstream and put them either back into your poop or into your bladder. Now if it was just the toxins it would be a nearly solid lump, or a bunch of paste.
So in your bladder particularly these waste products need to be diluted with water. So your kidneys extract water from your blood basically to rinse away the toxic stuff .
Now I’ve massively oversimplified this, but the important takeaway is to understand that it’s not like your digestive tract is piped into your kidneys or bladder by some sort of specific plumbing. It’s a whole bunch of processes .
So your body actually makes more water than you consume, but it needs to use up that water to regulate your temperature and get rid of waste products. So you end up needing to drink more water on top of the water your body makes out of the sugar and oxygen.
And your body uses this water for all sorts of other stuff because you are mostly made out of water. Like all of your cells are basically little tiny bags full of chemicals that are diluted in water.
Every stage of every process that your body performs requires and consumes or produces water.
So basically your body distributes any water you drink throughout your whole system. Your system uses it where it must. And some of that use is to rinse away the byproducts of your body doing its business.
TL;DR :: The constant job of regulating how much water is in your bloodstream is a vital process that involves almost every piece of your body. When you need extra water it is absorbed from your digestive tract. When you need to get rid of water it is expelled as urine, sweat, or the mist of your breath in various ratios.
