On a typical day, how much aqueous fluid does the average adult take in?

1. Daily fluid balance requires intake to roughly match output. 2. The average adult intake is about 2500 mL of aqueous fluids per day. 3. Roughly the same volume, about 2500 mL, leaves the body daily by various routes. 4. So 2500 mL is the correct daily intake figure. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 26 "Fluid, Electrolyte, and Acid-Base Balance", p.1256 §Water Balance_
