Comment on When two people kiss, they form a long tube from one anus to the other

Both 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.

The urethra is still separate from the digestive system though.

  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

    Wrong, pee is stored in the balls.

    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.
