The loop of Henle has a thin descending limb ... The cells here are permeable to water and thus the salt and urea concentration rises within the fluid by the time it reaches the bend.

According to an older 2012 article, the main function of the medulla is to regulate the concentration of urine. As fluid passes through the medulla, the loop of Henle and the collecting ducts ...

Urinary concentration depends on normal function of the countercurrent multiplier, which requires both active transport of sodium chloride in the thick ascending limb of the loop of Henle and ...

Urea transporter (UT) proteins facilitate the passive transport of urea driven by a concentration gradient ... UT-A2 in thin descending limbs of the loop of Henle, and UT-B in descending vasa ...

The calcium-sensing receptor (CaSR) expressed by the kidney can control renal calcium absorption and regulate blood calcium concentration ... of the loop of Henle. The researchers then performed ...
