The highhydrostaticpressure forces small molecules in thetubular fluidsuch aswater,glucose,amino acids,sodium chlorideandureathrough the filter, from the blood in the glomerular capsule across the basement membrane of the Bowmans capsule and into therenal tubules. This process is called ultrafiltration; The resulting fluid, viually free of large proteins and blood cells, is referred to as glomerular filtrate, or ultrafiltrate. Fuher modification of ultrafiltrate, by reabsorption and secretion, transforms it into urine. It can pass through the larger fenestrate it cant pass through the filtrate slit diaphragm between the podocytes.
