While these cells are dying water is entering the bloodstream and being transported to the kidneys to flush out the excess salt, destroying your cells and leaving your body unable to complete basic tasks. In an emergency situation you can remove the salt from salt water by boiling the salt water and collecting the water vapor with a separate instrument.
Water boils at a lower temperature than salt, leaving the salt behind. If you are able to condense the water vapor into a pure form you will be able to safely hydrate yourself. However, in general salt water should not be consumed and this should be considered a last resort.

What Happens When You Drink Salt Water Salt water contains a much higher concentration of salt than your body requires to survive, and in fact a higher concentration than it can safely handle. Why Too Much Salt Is Deadly When too much salt enters the body it disrupts your ability to naturally regulate the amount of water in your cells.
How to Safely Drink Salt Water In an emergency situation you can remove the salt from salt water by boiling the salt water and collecting the water vapor with a separate instrument. Drinking Water Health and Wellness Giuggio Updated: Aug 23, Have you ever been minding your own business on an elevator when an aggressively perfumed person stepped on? What happened? Nope, it wafted all over the elevator so that everyone could smell it. That's diffusion in action. This net transport of matter from a region of high concentration to a region of lower concentration is happening all the time [source: Gross ].
When it comes to diffusion and saltwater though, human cells have biological membranes, which can prevent salt from freely waltzing into our cells. Although our bodies can normalize sodium and chloride concentrations to an extent, dealing with extremely high concentrations of salt in the blood is challenging.
That's because a cell's membrane is semipermeable — although sodium, chloride and other substances may not be able to easily diffuse in and out of the cell, water can. When the salt concentration is higher on the outside of our cells than on the inside, water moves from the inside to the outside of the cells to correct the imbalance.
The attempt to equalize the concentrations of matter on both sides of a semipermeable membrane is called osmosis. If you're consuming seawater, the results of osmosis are spectacularly disastrous. Remember the salinity of seawater is almost four times that of our bodily fluids.
If gone unchecked, the net transfer of water from the inside of your cells to the outside will cause the cells to shrink considerably — and shrinkage is never good. Unless you drink a lot of fresh water, the body's regulatory mechanism in this situation is potentially fatal. With seawater, the change in sodium concentration outside our cells is the main culprit. In order to regain an isotonic state, a must for cell survival, the body attempts to eliminate the excess sodium from its extracellular fluids.
It secretes urine. It is okay to drink the water if you are stranded on a body of freshwater, at least from an osmotic pressure perspective.
Osmotic pressure is also thought to be important—in addition to capillary action—in getting water to the tops of tall trees.

It is the equivalent of a column of water 84 m tall. Answer 1. Summary Osmotic pressure is caused by concentration differences between solutions separated by a semipermeable membrane, and is an important biological consideration.
