This is an attempt to answer, not "the" answer.
I question the ability to inject a single red blood cell (erythrocyte) with water intravenously. Honestly you would need a very small syringe and a microscope to complete this procedure.
However if you did manage to do so, my guess is that the cell would break apart (lyse) from the sudden increase in pressure, ultimately destroying the cell.
Liquids given intravenously are solutions in water so they are mixtures not compounds.
If a red blood cell is placed into a hypotonic solution then the water concentration inside the cell is lower than outside the cell. The salt concentration is higher inside the cell than outside. So, due to the process of osmosis (water will travel from an area of high concentration to an area of low concentration) and the water will enter the red blood cell, increasing the pressure inside the cells. Red blood cells only have a thin membrane, they therefore can not cope with this high pressure and will eventually burst.
you will probably die but im not sure
Blood does not mix with water because blood is thicker and more dense then water. That is why if you put both in a container the blood will sink to the bottom and the water will rise to the top.
You should not do this - it could kill you. However, salt and water mixed to match the osmotic potential of your blood can be introduced via a vein as a saline drip. This drip should of cause ONLY be prescribed and administered by professionally trained and qualified medics. The treatment is used to rehydrate a patient.
An isotonic solution such as saline must be administered intravenously to maintain a proper concentration gradient. Water is hypotonic in relation to red blood cells and will cause the water to flow into the cell bringing about hemolysis. - S. Alam
Blood and blood cells contain certain amounts of various ions, meaning that distilled water would be highly hypotonic in comparison. The osmotic pressure would cause the water to enter red blood cells, causing them to swell and burst.
Blood in the Water match happened in 1956.
Nothing - peoples skin is water (and blood) proof.
If water was not reabsorb blood volume and blood pressure would drop. A person could not live under such circumstances.
since there were no enough water and salts reabsored, there woulnd't be enough blood volume, and blood pressure will be decreased.
it would shrivel up
You would need your red blood cells to be in an isotonic solution because they need the same amount of water moving into them as moving out so that they don't contract (plasmolysis) or burst (lysis). If put in a hypotonic or hypertonic solution, cell destruction could occur easily.

If they are centrifuged and distilled water is added, they will burst immediately
If human blood is put in salt water, the water molecules in the human blood will lead to the lower concentration of water molecules. This process is called diffusion- water molecules going from high concentration to low concentration.
