Hi... Can anyone illustrate me that when something gets stuck in your nose like water for example or something like fly, where does it move? I mean i literally want to know where does the passage the nasal cavity leads to. To brain or to the stomach. I've heard that it leads to the digestive system i.e. stomach. Could you people please tell me the exact anatomy of human nasal cavity with proper reliable medical information. If a small bee gets in your nose will it move to the stomach. Also do our nose consists of any sort of fluid like the wax in ears for killing insects in case they arrive there. Is the brain totally covered by the skull? can any insect crawl up through your nose into your brain? As far as i have seen the human nasal anatomy pictures on the web, it is leading to the stomach..But i need some information from medical personnel if there are some on yahoo answers. What kind of fluids are there in our nose, if there are any!!! Please show some guidance. what if an ant crawls in your nose? where it will go.. Thanks a a lot!!!
