WebNephron processing of urea is complicated, but basically up to 50% of filtrate urea is excreted. Tubular secretion also removes excessive potas-sium from the body. Nearly all potassium ions in the filtrate are reabsorbed in the proximal convoluted tubule and ascending nephron loop. Therefore, almost all potassium in the urine is derived from ...
