    The ears are connected to the throat via the Eustachian tubes. Those tubes are the reason why you can swallow and equalize the pressure in your ears when you are diving or in an airplane. Noses are connected via the sinus cavities.

        I put liquid into my body.

        My body digests this liquid.

        My kidneys digest it into pee.

        Pee comes out my urethra

        Done and dusted

          Yes, but there’s no single “tube” from your intestines to your kidneys. Your intestines absorb the liquid and then send it through a branching network of tubes which eventually end up at the kidneys.
