Answer :

Average osmotic pressure of human blood is 7.8 bar at 37 degrees.

Osmotic pressure is the minimum pressure that must be applied to a solvent to prevent that from going into a solution by osmosis. Or simply its a pressure of solution preventing solvent entry.

In blood the plasma proteins especially albumin exerts osmotic pressure. This results in indrawing of water to capillaries.

So when osmotic pressure of blood is high water absorption and reabsorption increases in body.

When osmotic pressure of blood increases plasma will gain more water in circulation from interstitium.

This is the reason of oedema in albumin deficiency. Decrease in osmotic pressure of blood result in more fluid to interstitium.

Polydypsia in diabetes mellitus is also due to increased osmotic pressure by increased glucose in blood.

Simply

LOW OP -----water---------> HIGH OP

Water moves from low osmotic pressure to high osmotic pressure.
