How do our ears not flood when we go underwater?
In: Biology
The ear drum creates a seal in the ear canal. The inner ear is connected to the eyes and nasal cavity by a canal called the Eustachian tube, which is why some people can take a gulp of milk and squirt it out of there eyes or blow smoke out of their ears. Normally the inner ear is sealed and the Eustachian tube only slightly opens to stabilize air pressure and to drain fluid in the case of an ear infection or water stuck in the ear from swimming.
