"WebUrine becomes more concentrated; The efficiency with which the kidneys filter the blood can be measured by the rate at which they remove a substance called creatinine from the blood. The rate at which they filter the blood is called the glomerular filtration rate (GFR). In 24 hours, a person excreted 1660 mg of creatinine in his urine.

WebUrine is formed in tubules by three steps, filtration, reabsorption, and secretion in the kidneys.

WebThe tubular filtrate becomes hyperosmolar (concentrated) under the action of ADH in the collecting tubules. For ADH to effectively allow water absorption, a medullary interstitial concentration gradient must be established by NaCl absorption without water in the ascending limb and the vasa recta. WebSo, the glomerular filtrate concentrates as it moves down through the descending limb. Reabsorption is minimum in the ascending limb. This limb is impermeable to water but electrolytes can be transported actively or passively. So, as the concentrated filtrate moves upward it gets diluted due to the passage of electrolytes to the medullary fluid.

WebWith water loss, urea left behind in the urine makes the urine more solute concentrated till it reaches the CD c) urea recycling causes a buildup of urea in the medulla: urea (and water in the presence of ADH) leaves urine in the CD (permeable to urea) and is “recycled” back into urine in the descending and thin ascending limbs of LOH which are permeable to urea.
