Question99:-The Donnan effect on the distribution of ions has following effects in
the body.

i. Because of charged proteins in plasma, there are more osmotically active
particles in the plasma than in cells.

ii. Normal cell volume and pressure depend on Na, K ATPase.

iii. Because at equilibrium the distribution of permanent ions across the membrane
is asymmetric, an electrical difference exist across the membrane whose
magnitude can be determined by the Nerst equation.

iv. Because there are more proteins in the plasma than in interstitial fluid, there is a
Donnam effect on ion movement across the capillary wall.
