If I drink a liter of water, how much of the water is absorbed and used by my body, and how much just goes right through me?

All of it goes through you and all of it is absorbed and used by your body, mostly as a solvent. Even when you just piss it away, you do so along with some salts, and that's still the water being used by your body for a specific purpose.
