      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.
