Wait… do holes that meet up with other holes count as separate holes? The nostrils meet up with the mouth hole but then combined they go through to the anus. Do those count as three distinct holes, since looking at each of them individually they would count as a hole? Or would there be one hole with… four openings?
ETA: I have more questions. Do all the openings need to be open to still be considered a hole? Is it only a hole if all my sphincters are open and my mouth is open? If I’m getting choked but my mouth is open and I’m trying to breathe, does my mouth to nostrils count as a hole themselves? Do my nostrils automatically count as a hole as long as one or both isn’t stuffed up?
I’m really curious how you got that number? I guess eye sockets aren’t counted, as topologically with how many of the tubes connect, it’s probably something weird.
4 lacrimal ducts, 2 nostrils, 1 mouth and 1 anus = 8 interconnected holes. Subtract 1 (because a proper donut hole needs both an entrance and an exit) and you get 7.
I guess it could be argued that women have an extra hole, as there is a passage through each fallopian tube into the pelvic cavity.
OP claimed there are 7 holes. Holes don’t need an exit, and I’d like to know where you think inserting something into an orbit will naturally come out in a person you want to survive the experience.
Correct, that’s not a hole in the topological sense. A famous example is a coffee cup: the handle is a (through-) hole, but the inside of the cup is not. As such, the coffee cup is isomorphic (=identical in terms of their overall structure) to a donut.
“The human body has 7 holes” is most likely a reference to [this vsauce video], and admittedly said video is the entirety of my knowledge on topology;
that should answer “I’m really curious how you got that number”, and… probably the comment I’m replying to?
I’m not sure I understand your rhetorical curiosity, but humans usually insert food in their mouth which is then pushed through the entire through-hole while being exposed to gastric acid and whatnot;
another example are tears, entering the openings in the eyelids and coming out of the nostrils.
Urine is instead chemically produced by the kidneys, and, unless you consider the space between molecules (which AFAIK is not within the domain of topology), that doesn’t count as one shape traversing a through-hole of another.
The human body has 7 holes
a vagina alone has 6, so this is hardly accurate.
No, in topology those are pretty much just indents (I.E irrelevant)
For a hole to be considered a hole, it has to go through an object.

see, this is why everyone hates topology and their silly yet weirdly true rules.
Ponders a klein vagina…
Booooo. We all know what a hole is, don’t bring topology into this. I’ll give you a plate for your drinks at my house if you pull this silliness.
Wait, do you consider cups to be portable holes for liquids?
If you don’t see the difference between a cup and a plate because they’re the same topologically then I’m gonna use them interchangeably around you.
50 cent had 12 briefly.
Pretty sure 7+9 is 16.
I don’t follow in the dogma of the ears and nose, since you can’t fuck them…
As opposed to the bullet holes then?
Exactly! You’re getting it now.
That’s quitter talk.
Fewer when part of a human centipede.
I would argue that being part of a centipede doesn’t reduce the number of holes, it just creates a more scenic route to the outside.
When do I get to shit in anybody’s mouth‽
Everyone’s?

Mouth/anus is just one hole since humans are doughnut shaped.
But it leaves out the urethra
It’s not a through-hole, because you can’t insert a small object into it and have it come out of some other opening
OP claimed there are 7 holes. Holes don’t need an exit, and I’d like to know where you think inserting something into an orbit will naturally come out in a person you want to survive the experience.
If you count holes that don’t have an exit, there are thousands of pores you could count
Topological holes are through-holes. If there is no exit, you could continuously deform the shape until the hole is gone
So if i dig a hole in the ground that’s not a hole? Should we pivot to divot?
Correct, that’s not a hole in the topological sense. A famous example is a coffee cup: the handle is a (through-) hole, but the inside of the cup is not. As such, the coffee cup is isomorphic (=identical in terms of their overall structure) to a donut.

So we are really just a big cup?
donut != cup

In topography a donut and a cup are equivalent shapes.
cup != mug
