Answer 12

We need water because 70% of our body is just water. The other 30% is just chemicals. If we let just 5% of our body's water evaporate (turn to water vapour and go into the clouds) then we'd over heat and the electronic signals in our body that make our muscles move (including our heart) would be unable to conduct and travel through any thing and our heart would stop working.

Answer 16

Many many reasons - without water our cells would actually burst.

For example, think of the slug.  Cover it in salt (which means the water is drawn from its body to the outside), it then begins to die.  The cells have burst.

Not that a human would "dissolve" in a similar way - but its a good enough example to give you an idea of the seriousness of lack of water.

Truely though, I could lecture you for hours on all the different processes that require water - but i think my cells might burst at the boredom of it all
