How Is Urea Reabsorbed In The Kidney?

by

How Is Urea Reabsorbed In The Kidney? Urea is freely filtered, 50% are reabsorbed in the proximal tubule with the reabsorption of water (solvent drag). Urea is secreted in the thin ascending limb of Henle loop, so significant amounts of urea reach the distal nephron. In the collecting ducts, urea is reabsorbed together with water.

Where Is Phosphate Reabsorbed In The Kidney?

by

Where Is Phosphate Reabsorbed In The Kidney? Within the nephron, approximately 85% of phosphate reabsorption occurs within the proximal tubule (Figure 3B). Where is phosphorus reabsorbed? Approximately 7 g of phosphorus is filtered daily by the kidney, at physiologic levels of serum phosphorus, of which 80%-90% is reabsorbed by the renal tubules and the remainder
