What forces promote Glomerular filtration? What forces opposes them? What is meant by net filtration pressure?

Explanation

Glomerular pressure is the chief force that pushes water and solutes out of the blood and across the filtration membrane. The glomerular blood pressure (approximately 55 mmHg) is much higher than in other capillary beds. The two opposing forces are contributed by the plasma proteins in the capillaries. These include, colloidal osmotic pressure (30. mmHg) and the capsular hydrostatic pressure (15 mmHg) due to the fluids in the glomerular capsule. The. net filtration pressure of 10 mmHg is responsible for the renal filtration.
