glomerular pressure
Quick Summary
Glomerular pressure is the blood pressure within the glomerular capillaries, which provides the energy for filtration in the kidneys. This pressure is influenced by systemic blood pressure and the tone of the afferent and efferent arterioles.1
Normally, glomerular pressure is about 45 mmHg, higher than in other body capillaries. This pressure drives the filtration of plasma (minus macromolecules like proteins) from the glomerulus into Bowman's capsule, a key step in urine formation and waste removal from the blood. Changes in arteriole constriction can significantly alter blood flow, glomerular pressure, and the filtration rate.12
