Question

Quizplus · Accepted Answer

Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. Since red blood cells have a high concentration of dissolved ions, when placed in pure water (which has a lower concentration of solutes), water moves into the cells, causing them to swell and eventually rupture. This process is known as hemolysis.
