Web6 jul. 1999 · Ultrafiltration of blood during formation of the primary urine in the glomerulus is one of the central functions of the human kidney ( 1 ). Structurally, the glomerulus is a tuft of anastomosing capillary loops surrounded by the Bowman’s capsule leading the primary urine to the tubular system. WebThe filtration membrane is formed by the endothelial cells of the glomerular capillaries and podocytes. They are arranged in a sandwich-like assembly to permit the filtration of water and small...
