Preferred Label : descending limb of loop of Henle;
Uberon definition : the portion of the renal tubule that constitutes the proximal part of the loop of
Henle, has low permeability to ions and urea, and is highly permeable to water; it
consists of an initial short thick segment lined by low simple cuboidal epithelium
and a long thin segment lined by simple squamous epithelium; however, this distinction
is not as important physiologically as in the ascending limb, so often the two are
treated as one structure;
