WebUrea is both reabsorbed and secreted (recycled back into the filtrate) during passage of the filtrate through the rest of the tubule of the nephron; the net effect of these two processes results in around 30-50 % of the filtered urea appearing in urine. WebUrea. 50% of filtered urea is reabsorbed in the proximal tubule. However the concentration of urea actually increases thanks to the reabsorption of 70% of the filtered water in the same portion of the nephron. Also Know, how is urea concentrated in the filtrate? How does urea pass through the kidney membrane?

WebUrea excretion is thought to result from filtration curtailed by some passive reabsorbtion along the nephron.
