The Na + / K + / 2Cl " transporter in the ascending limb of the loop of Henle helps to create a gradient by shifting Na + into the medullary interstitium.
42.
Tubulo-interstitial is used because the problems that occur in this disease result as a consequence of atrophy, of tubules, of the loop of Henle and fibrosis of the medullary interstitium.
43.
The interstitium of the kidney increases in osmolarity outside as the loop of Henle descends from 600 mOsm / L in the outer medulla of the kidney to 1200 mOsm / L in the inner medulla.
44.
By means of a countercurrent multiplier system, which utilizes electrolyte pumps, the loop of Henle creates an area of high urea concentration deep in the medulla, near the papillary duct in the collecting duct system.
45.
Using this combination, diuretic effects will occur at two different segments of the nephron; namely, the loop diuretic will act at the loop of Henle, and metolazone will act at the distal convoluted tubule.
46.
It is these nephrons which are responsible for the development of the osmotic gradients in the renal medulla, which are used to concentrate urine . These nephrons have a longer loop of henle than cortical type of nephrons.
47.
Conversely, between 10 % and 30 % of the total nephron population is composed of mammalian-type nephrons, which are located in the innermost area of the kidney, have complex glomeruli, and contain loops of Henle.
48.
Blood from the efferent arteriole, containing everything that was not filtered out in the glomerulus, moves into the peritubular capillaries, tiny blood vessels that surround the loop of Henle and the proximal and distal tubules, where the tubular fluid flows.
49.
:: : says that urine production is reduced in a dehydrated camel, but with no indication of whether that's a function of the kidneys or the bladder . " Camel kidneys have long loops of Henle and can manage salts.
50.
The latter feature is due to the presence of elongated loops of Henle; these are much shorter in birds, and not truly present in other vertebrates ( although the nephron often has a short " intermediate segment " between the convoluted tubules ).
