Blood cell RBC Osmosis

Blood cell (RBC) in different solute concentration (0.9%, 5%, 0%).
This is a unique experiment to show our RBC in different solute (salt) concentration.
In 5% NaCl solution ( 5g in 100ml distilled water), we found RBC gets crenated as water comes out of them (Exosmosis), whereas in distilled water (0% NaCl), water enters inside RBC (Endosmosis) and it keeps on getting swelled and then it burst ( as there is no cell wall in animal cell).
So, ultimately we see only RBC - membrane ('Ghost' cell).
But if we see same RBC in 0.9% NaCl (900 mg in 100 ml distilled water),
RBC remains in normal shape (about 8 micron diameter and 2 micron thickness).
That is why we call this concentration (0.9%NaCl ) as NORMAL SALINE.
We give this solution whenever any patient comes in hospital which severe water or blood loss .
This is a simple experiment but it involve puncture of skin so it should be done with utmost care.
