NaCl+CaCl{2} isotonic with sea water, hypertonic, or hypotonic solutions.
All nose lotions should be alkaline, and isotonic with the blood plasma.
Whichever drug is chosen, a small quantity of chloride of sodium should be added in order to make the solution isotonic with the blood serum, and thus to render it practically non-irritant.
If in the saline solution we place a coloured isotonic drop between two coloured hypertonic drops, all the figures and movements of karyokinesis appear successively in their due order.
Between isotonic solutions the surface is plane, whilst it is curved between solutions of different osmotic pressures, the convexity being directed towards the hypertonic solution.
The method depends on the principle that solutions isotonic to the blood corpuscles and to the blood serum will not alter the volume of the blood corpuscles, whereas hypertonic solutions decrease that volume.
Such a solution would not indeed produce an exchange of water with the egg, but it would set up an exchange of electrolytes, since there would be a difference of their osmotic pressure in the egg and in the new isotonic medium.
The solution is therefore practicallyisotonic with the stimulated muscle.
We have just seen that a living cell, whether vegetable or animal, is not altered in volume when immersed in an isotonic solution that does not act upon it chemically.
Take, for instance, two isotonic solutions, one of salt and another of sugar.
When a muscle is immersed in an isotonic salt solution it does not change in weight.
Even {47} with isotonic solutions there will be a transfer of the solutes if these are of different chemical constitution.
NaCl is therefore isotonic to the contents of the red blood corpuscles, to the serum of the blood, and to the cells of the tissues.
Saline Solution+, or normal, or isotonic salt solution, as it is called because of its close approximation to the blood serum, consists of a solution of 7 per cent.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "isotonic" in a variety of sentences. We hope that you will now be able to make sentences using this word.
