Urethra isn't a hole though, it's just a depression. Mouth and anus are the same hole.

Your nostrils, eyes, and ears are also connected to the inner-outside part of your body via the sinuses. So we're not doughnuts, we're something much stranger with 8 holes all connected in the middle.

Urethra and vagina are pockets, not true holes, since they don't go all the way through.
