Differences in osmotic pressure inside and outside a red blood cell can result in crenation (shriveling) or hemolysis (rupture). nplete The diagram shows three solutions: an isotonic solution, a hypertonic solution, and a hypotonic solution.

Answer 1

Due to osmosis, solvent molecules flow from a solution of lower concentration (of the solute) to the ha a solution of high conc. (of the solute). Two solutions having same osmotic pressure at a given temperature is known as isotonic solution. osmotic pressure associated with fluid inside the blood cell is equivalent to 0.9% (m/v) nach solution. If a red blood cell (RBC) is placed in an isotonic Solution no osmosis will take place. If a red blood cell is placed in a hypertonic solution (conc. greater than 0.9% M/ Nad), water will flow out of the cell through the se cell membrane and the RBC would shrink. It is crenation If a red blood cell is placed in hypotonic solution (conc. < 0.97. my Nad solution), water will flow into the RBC and it would supture. It is hemolysis. Hypertonic Hypotonic Isotonic No change for RBC crenation Hemolysis
