If you hold you skipper underwater, near you mouth shut..?

how comes your head don't overrun up with dampen through your nose and ears?If you hold you skipper underwater, near you mouth shut..?
as for your ears, the tympanic membrane, or eardrum blocks marine from entering your inner ear. water does enter your ear however not to a point specifically highly distinguishable due to the fact of the short distance of the ear conduit which we see as the hole leading into the ear. the muzzle does not fill next to water because significantly because when ones mouth is closed within is still a slight positive pressure of ear residing in respectively nostril so if you are not inhaling through the nose in attendance should be no water within the nostrils. if you are upside down water displaces the heavens in the nostrils down to the mouth allowing it to enter into the antenna.
Because your body naturally stops this from up. How the hell would water procure into your head through your ears anyway??
pressure from inside is greater than that river
HELLO,
BECAUSE THE ANATOMY OF YOUR BODY MAKES THIS IMPOSSIBLE. CUTE QUESTION THOUGH, LOL.
