What can happen to a red blood cell if placed into a solution that is more dilute than its own cell contents?

The red blood cell is an animal cell therefore has no cell wall and will change its shape and seize dependent on the concentrations of solutions around it. When placed in a more dilture solution a red blood cell will have water move into the cell via osmosis. This will cause the inside of the cell to swell up and sometimes burst. Bursting of red blood cell is known as haemolysis.
