Question

Why it is necessary to maintain a normal osmotic concentration of the blood?

Answer 1

Osmosis is the diffusion of molecules or water from a place of higher concentration to a place of lower concentration through a semi permeable membrane. it necessary to maintain normal osmotic concentration of the blood because If the concentration in blood is higher than in the surrounding tissue, then the blood cells will try to expel their water from the tissues to the blood, which might cause blood cells become harder and cannot move through the blood vessels as easily while if the concentration of the blood is lower than the surrounding tissues, then water will move from the blood to the tissues.
