What happens to Red blood cells when added with water?

When red blood cells are added to water, they undergo a process called hemolysis. This means that the red blood cell membranes rupture and the contents of the cells spill out into the surrounding water.

The process of hemolysis occurs because the red blood cell membrane is semi-permeable. This means that it allows water molecules to pass through it, but it does not allow larger molecules, such as proteins, to pass through. When the red blood cells are added to water, the water molecules move into the cells, causing them to swell and burst.

Hemolysis can also occur if the red blood cells are exposed to other substances that damage the cell membrane, such as detergents or acids.

The process of hemolysis is important because it is a way to destroy red blood cells. This can be necessary for medical reasons, such as when someone is receiving a blood transfusion or when they are being treated for a blood disorder.
