|
Term
| How would you differentiate HYPOtonic and HYPERtonic their e=affect on blood cells? |
|
Definition
| If red blood cells are placed in a solution with lower solute concentration than is found in the cells, water moves into the cells by osmosis, causing the cells to swell and eventually burst (hemolysis); such a solution is hypotonic to the cells, while cell cytosol is hypertonic to the plasma. |
