Actually it does.. once you die. Your body has to keep all the fluids in it moving around and uses the blood stream and other organs to do so. When blood vessels are severed, the tend to contract close off in order to prevent the very thing you are talking about. If the vessel cut is large enough and can't 'seal itself off' then you simply bleed to death.

But even when you die and your body it's injured for the fluids to run out, gravity still does it's thing. Say you die laying on your back. After about 4 hours, your body fluids will begin 'pooling' at the lowest point. There will be a darkening and puffyness at the lowest points were all this fluid is collecting. This is call dependent lividity (I hope I spell that right).

So... as long as your body is alive... your fluids stay inside and move where they are supposed to. Us humans are pretty amazing works of art and machinery!

Hope this answers your question!

the answer is quite simple my friend, its called perripheal shut down,
the body is very clever and when it suffers an injury causing blood loss it can restrict or cut off the supply to the extremities of the body, the body needs the major organs, heart,brain ect to survive , it does not need hands and feet, when the blood level drops to a dangerous lebvel the body closes of the supply to the limbs and concentrates on the torso and brain..
thanks

It's called cells.
fluid, blood, water, etc are mostly trapped in cells in your body.
