Which part of the male reproductive system store the sperm? Water or salts (chiefly NaCl) are excreted by the kidney to keep the blood isotonic with the cells. If the pressure greater than the osmotic pressure is applied the water (solvent) from the solution side starts moving towards pure water.

So, if P is the pressure of the solvent and Ps is the vapor pressure of the solution, the relationship between vapor pressure and osmotic pressure is given by: Relative lowering of vapor pressure is the relative change in pressure with respect to the added solute. If you store contacts in distilled water, the salt concentration is higher in the eye fluid and water flows out of the contacts; slowly drying them out. Osmosis Osmosis In Living Organisms.
