What would happen to water absorption if the osmotic pressure if the blood were to increase above normal? explain.

Expert Solution

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.

Blood generates an osmotic pressure equivalent to the pressure generated by a saline solution that is 0.900 % m/m NaCl in water. This solution, used for intravenous fluids in hospitals, is called normal saline solution. Assume the solution density is 1.00 g/mL. a) What is the molarity of normal saline? b) What is the mole fraction of water in normal saline? c) How many sodium ions are there in one milliliter of this solution? d) How many grams of sodium...

The osmotic pressure of an unknown substance dissolved in 100 mL of water is measured at 298 K. The concentration of this substance is 25.5 kg m–3 and the osmotic pressure is 4.50 x 104 Pa. a) Determine the molecular weight of this substance. b) Calculate the change in the freezing point of water caused by the addition of this substance. (Keep in mind that the density of a dilute aqueous solution is approximately 1 g/mL).
