WebTo reach the hypertonic environment of 1200 mOsm, the kidneys take advantage of filtered urea to help reach those high numbers. Urea is a waste product of the breakdown of product of protein metabolism. The kidney nephrons contain one more section of tubules that ultimately determines the fate of urine. That section is the collecting duct. WebThis is accomplished as follows: 1. Normally the glomerular filtrate has a similar osmolality to plasma (300 mOsmol/kg). In the descending limb of the loop of Henle, the NaCl cannot be absorbed, but water is passively resorbed (#1), creating a hypertonic urine (>1200 mOsmol/kg) as it enters the ascending limb. 2.

WebOct 1, 1999 · In order to account for the formation of hypertonic urine in the presence of ADH, Homer Smith had to postulate the existence (in distal segments) of an additional active component of water reabsorption, T X (H 2 O) in Figure 2, i.e. a component working against the gradient of osmotic pressure. WebThe flow of blood through the two limbs of vasa recta is also in a countercurrent pattern. The proximity between the Henle’s loop and vasa recta, as well as the countercurrent in them, help in the formation of hypertonic urine and conserve water. Hence, the function of counter current mechanism in kidney is to conserve water. population of swannanoa nc
