~Don't look now, but I think yours did (or it's too full of stone to absorb water). And you should.

Well, there really isn't any way for the water to get into your head. All the openings in your head that would be large enough to let a significant quantity of water in, lead to other areas of your body. Your nose and mouth lead to your lungs and stomach. When you hold your breath, the air pressure in your lungs will keep the water out. You can get water in your sinuses ("water up your nose") if the air pressure gets disrupted, but your reaction would be to get out of the water and expel it before you aspirate it. Your ears have a membrane, your ear drum, that prevents water and other things from entering your inner ear. And even if there was some hole in your head that water could get into, it wouldn't have anywhere to go. Your head is NOT empty (hopefully!). The space where your brain is doesn't just contain your brain, but also cerebra-spinal fluid, which cushions the brain, all of which is surrounded by the derma. This is a thick membrane that also protects your brain from smacking into your skull. So water doesn't fill your head when you immerse it because it can't get in and wouldn't have anywhere to go anyway!

you drown not because your head is filling with water... but because your are not breathing in oxygen and therefore the blood delivered to your brain cannot support the brain cells which die, shutting down the brain. Lungs are often found full of water because of gasps of breath while under water, or after death the absorbtion of water...

Here's some food for thought...water takes the path of least resistance...Just think about where the big openings are located on the body... For example, canals of your body, like your nose or your mouth for example lead to your lungs and esophagus, this is one area where the water might go.. As for other ways liquids enter and exit body systems, that is another story...molecular physiology and transport systems might not make for a good discussion here. Good luck!

You just stop breathing,your brain stops functioning!
