Question

What role does hydrostatic/filtration pressure have in the physiology of glomerular filtration?

Answer 1

Answer:

The answer to the question: What role does hydrostatic/filtration pressure have in the physiology of glomerular filtration, would be: this pressure from the blood against the mesh of the glomerulus is the one that ensures that there is a filtration rate at all. When this pressure drops, the kidneys will stop filtration altogether, and another series of steps will be taken to bring hydrostatic pressure in the blood back up.

Explanation:

The production of urine, and the filtration of the blood by the glomerulus is a process that depends, most of all, on the pressure that the blood comes with into the kidney´s filtering unit. When this pressure is appropriate, the glomerulus will filter out water, nitrous wastes, and other such filterable elements, so that they can be excreted in urine. However, when this pressure drops due to loss of blood volume, or an excessively high blood pressure, the kidneys themselves respond by stopping filtration and sending signals that will work to restore normal blood volume and correct hydrostatic pressure to the glomerulus. This is why hydrostatic pressure is so important in filtering of urine.
