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.

No, the vagina is topologically a hole, as the uterus with the Fallopian tubes has two direct openings into the abdominal cavity (another objectionable “design” choice).

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.

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.

why is the nose only one hole?
accideath@lemmy.world 2 months ago
Nose is two. Your butt isn’t one. Or rather, your mouth and nostrils would be the entrance and your butt is the combined exit of those three holes. If you don’t count the nostrils, you only have one hole. A hole always goes through something, otherwise it’s just a cavity. And also, holes only count from one side. Your butt and mouth are the same hole, just from different ends.
