It all comes from your digestive tract. Unless you're getting iv, subq or even more interesting io fluids. Though if you're getting io fluids your kidneys are likely getting fucked up enough to not produce urine for awhile and if you're getting subcutaneous fluids you're likely a cat or a dog or something.
While that would still be the digestive tract, I would also like to say that liquid absorption works from both ends equally well. In theory you can never drink from your mouth and still be perfectly hydrated ;)
To be sure, the Murphy drip was used extensively in WW1. Kinda makes you wonder what those fucking WW2 coconut iv guys were doing when you had perfectly fine access from the bottom that could take boiled water full of pyrogens just fine. And if you're in enough of a volume depleted state where a Murphy drip can't help due to vasoconstriction then all that potassium from a volume infusion of coconut ivs is gonna kill ya anyway.
I work in hospice and Macy catheters have been incredibly helpful for symptom management in homes when patients need extra support and we're trying to avoid moving to inpatient.
