Does blood pressure affect gfr in kidneys?

Yes, blood pressure does affect the glomerular filtration rate (GFR) in the kidneys. GFR is influenced by the pressure in the glomerular capillaries, which is determined by systemic blood pressure. If blood pressure is too low, GFR decreases, potentially leading to impaired kidney function. Conversely, excessively high blood pressure can damage the glomeruli over time, affecting their ability to filter blood effectively.
