These vessels branch off the efferent arterioles of juxtamedullary nephrons ( those nephrons closest to the medulla ), enter the medulla, and surround the loop of Henle.
32.
Close to the loop of Henle and in the distal convoluted tubule of the nephron where much glucose has been reabsorbed into the bloodstream, SGLT1 transporters are found.
33.
Uromodulin excretion in urine follows proteolytic cleavage of the ectodomain of its glycophosphatidylinositol-anchored counterpart that is situated on the luminal cell surface of the loop of Henle.
34.
These structures include the vasa rectae ( both spuria and vera ), the venulae rectae, the medullary capillary plexus, the loop of Henle, and the collecting tubule.
35.
Bartter syndrome is also an autosomal recessive hypokalemic metabolic alkalosis, but it derives from a mutation to the NKCC2 found in the thick ascending limb of the loop of Henle.
36.
This reabsorption occurs throughout the tubule ( most, 60-70 %, of it in the proximal tubule ), except in the thin segment of the loop of Henle.
37.
The descending portion of the loop of Henle is extremely permeable to water and is less permeable to ions, therefore water is easily reabsorbed here and solutes are not readily reabsorbed.
38.
In the kidneys, elimination of potassium is passive ( through the glomeruli ), and reabsorption is active in the proximal tubule and the ascending limb of the loop of Henle.
39.
It functions in renal water reabsorption by building up a high hypertonicity, which draws water out of the thin descending limb of the loop of Henle and the collecting duct system.
40.
The ultrafiltrate is passed through, in turn, the proximal convoluted tubule, the loop of Henle, the distal convoluted tubule, and a series of collecting ducts to form urine.
