Distilled water causes cells to lyse, so injecting distilled water into a vein will cause some degree of hemolysis. Hemolysis is the rupture of red blood cells. A small amount of distilled water would quickly mix with the blood and would cause little to no noticeable damage. A large amount of distilled water would cause much more damage, not just limited to hemolysis. Among other things, large amounts of pure water introduced to the body would alter the electrolyte composition of blood, which could cause brain damage or cardiac arrest and death. This is why fluids are administered to patients as saline (which includes an appropriate amount of salt), and also why athletes prefer to drink fluids with electrolytes as opposed to pure water.
If it's not a lot of water, and the water and syringe/needle are sterile --- nothing. The question of course will be sterility, as if it isn't sterile, you've pierced the skin and may have introdued something into your system. I can't think of any medical procedure that would require this, at least without more information.
Water is hypotonic (containing no solute.) If you put a red blood cell in water, through osmosis (area of greater water to less water.) The pure water is said to be hypotonic. Hypotonic solutions cause rbc to burst or lyse. Because of hemolysis water injecting isn't advised.
nothing happens at all. a few of my friends and myself have done it, and nothing happens.
No. Not if the water is sterile and/or filtered
No where. HOW ABOUT YOUR CAROTID ARTERY IN YOUR NECK?
you can either pass or shoot the ball
If you poke your Vein with a needle, you will bleed slowly (nonstop), Painless but Suicidal.
you become a dog
A thrombosis is a blood clot in a vein. This usually happens after some injury to the body. I think the most common form of thrombosis is a deep vein thrombosis in the legs. When this happens there is swelling of the muscle, pain and redness.
You can use any vein. Inner arm veins are popular because they are easily found and conveniently accessible.
They shoot water from their mouth.
no they can shoot runny poo
earth+volcano+water... also hydro-thermal vein+earth=minerals
You die.
The grenade will be shot
