          I’m sure most people have more (topological) holes than one

          Both nostrils, for example

            The nostrils are connected to the throat through the sinuses as are the ear canals. Topologically making them all part of the same mouth-anus throughole.

              Not true, topolgically the route

              left nostril -> sinus -> right nostril

              is another hole. So is

              any nostril -> sinus -> mouth.

              ears have the eardrum, so they don’t count.

              For the more formal definitions of topological holes, look up Betti numbers, I think there’s a VSauce video about it? For humans, the number of holes is at least 3 (but I’m sure I’m missing many more holes). Unless you’re missing the entire septum.
