21. As the pore size drops from MF to NF, the osmotic pressure requirement increases. 22. The increased osmotic pressure forces water to flow into the cell and tissue swelling occurs. 23. However, the basic mechanism involves regulation of osmotic pressure . 24. Osmotic pressure is the " chemical potential of concentrated and dilute solutions of salt ".25. The osmotic pressure drives water back into the vessels. 26. The pressure required to stop the flow across the membrane is called the osmotic pressure . 27. As an aside, diffusive forces are also prominent in cell biology and creates osmotic pressure . 28. Some neurons in this organ are osmoreceptors, being sensitive to the osmotic pressure of the blood. 29. Some neurons in the SFO are osmoreceptors, being sensitive to the osmotic pressure of the blood. 30. Using these equations one can calculate the molar mass of solutes from the osmotic pressure data.
