Important note, if you take a straw that separates into two split straws (kinda in a “Y” shape) that from a topological point of view is two holes, because one is for one of these paths, and the other is an extruded hole on the side of the first path.
In topology you can’t break or mend material, but you can pull, stretch, squeeze and move it all you want. So you can move one of the split straw “legs” to the bottom of the whole straw, getting a shape similar to a “V”, it would look pretty much like a pair of pants. And topologically speaking it would be exactly the same.
So…
One straight hole for your mouth all the way down to your anus. Another two are there for your nostrils, that’s 3 already. The rest are for your tear ducts, which have two holes on the edge of your eye, (so four in total) which merge and then connect to your nose.
So a human, from a topological perspective, is just a seven holed doughnut. Also Vsauce made a great video about that, with pretty great animations.
Depends on the state of your esophagus, doesn’t it? If it’s closed (which it mostly is) then your mouth and nose holes go to your lung cavity. Your anus is also part of a cavity that goes through your intestines all the way up your throat and stops at your esophagus.
Its only a valve. Topologically speaking, the passage from the mouth to the anus only constitutes one hole.
The passage of air into the lungs is not a hole however, that is a cavity. Same difference with the vagina, that’s not a hole, that’s a cavity.
People are donuts!
No, since you have a nose. Topologically, people have 3 holes.
7, if the cut-off is 60 microns (tear ducts). Smaller than that, we’re essentially Swiss cheese.
Tbh, I was kinda hoping for someone with better biology knowledge than me to correct me. Thanks.
What are the the 7?

I am well aware that people have three topological holes. Matter of fact, I proved that years ago.
In this case, I only referred to one topological hole, from mouth to anus.
I never mentioned the nose, nor was that part of the topic in question.
Yum.
You don’t need that
Mmm
