Quizplus · Accepted Answer

The force for glomerular filtration is the blood pressure in the glomerular capillaries. This pressure is responsible for pushing the blood and its components through the glomerular filtration membrane and into the Bowman's capsule. The osmotic pressure in the glomerular capillaries is actually opposing this process, as it pulls fluids and solutes back into the capillaries. The fluid pressure produced by the displacement of the fluid in the lumen of the tubules occurs after the filtration process, as the filtrate moves through the renal tubules. ATP-dependent processes in the nephron are involved in reabsorption and secretion, but not in the initial glomerular filtration process.
