Loop of henle bbc bitesize
WebAbstract. The loop of Henle was early identified as a structure essential for the concentration of the urine, since it occurs only in birds and mammals, the two classes that produce urine with osmolality higher than the blood. Subsequent study of the loop of Henle has mainly involved its role in urinary concentrating mechanisms. http://www.yearbook2024.psg.fr/7g7Su9Y_ant-heart-diagram.pdf

WebThe loop of Henle emerges as a bending-out from this S-shaped tubule, and grows as an elongating loop, rather like the extending slide of a trombone. This looping growth does not disturb the relationship between distal tubule and glomerulus, so the problem of navigating to the correct glomerulus never arises (see Saxén, 1987 for a general review of the …
