Question

The kidneys function based on the movement of fluids across the filtration membrane. There are three different types pressure operating at the filtration membrane. List and explain how each influences net filtration pressure.

Answer 1

• The major force that tends to create a push for the water and solvent to the filtration membrane is Glomerular hydrostatic pressure (GHP).

• The other pressures are Capsular hydrostatic pressure and Net filtration pressure.

Step-by-step explanation:

• Glomerular osmotic pressure: creates pressure in the glomerular blood for the plasma protein to enter filtration membrane.

• Capsular hydrostatic pressure: it brings back the fluids into the glomerular capillaries.

• In mathematical term the net filtration can be sated as: Net filtration pressure = glomerular hydrostatic pressure - glomerular osmotic pressure + capsular hydrostatic pressure.
