Does the body have mechanics to prevent liquids from entering the body while underwater?

Like, when you go underwater why doesn t the water go up your rectum, through your intestines, into your stomach, up your esophagus, into your sinuses, etc. How come it doesn t go through your genitals / bladder, ears, etc. Or does it actually do all of this and we just don t notice somehow? If there is some muscle or mechanism to prevent this, what is it? How much water pressure would be required to breach it? Would you be able to survive? Would it feel weird?

    Water will "want" to go in the nose, ears and mouth. This is why divers have to equalize when they go down because the water pressure want to "go in:.

    THe bladder and rectum are not air filled so this wont happen. Water will not "press in" like the air filled areas of the body.

    For water to flow there has to be a pressure difference. In most cases like the rectum, vagina and urethra there is no pressure difference because we are mostly water. In the case of the lungs, you close your mouth and the air in the passageways is compressed as you go under the water so there is no pressure difference there either. Only if there is a pressure difference do you get water into the openings, such as when a woman water skis and drops her bottom into the water between the skis, the pressure of the water can enter her vagina and cause an internal rupture.
