    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.

            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.

              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.

              I did consider that in a comment I wrote deeper in the thread, but if you put it like that, the concept of “hole” doesn’t even make sense anymore

      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.
