Detailed explanation-1: -A lab tech performed a routine RBC count. The cells appeared shriveled and were difficult to count. What was wrong with the cell storage solution? It was hypertonic.
Detailed explanation-2: -A cell placed into a hypertonic solution will shrivel and die by a process known as plasmolysis.
Detailed explanation-3: -If blood cells are placed into a hypertonic solution, the cell will lose water and shrink as the water moves down its concentration gradient from the cell into the solution.
Detailed explanation-4: -What might happen to your red blood cells if you were suddenly unable to regulate the solute concentration of your blood and it began to rise? Your blood cells would shrivel because water would move out of the cells via osmosis.
Detailed explanation-5: -Cytolysis is observed when a cell is placed in a hypotonic solution. Due to the osmotic gradient, the water molecules will move into the cell resulting in swelling of the cell which will eventually burst and lyse.
