Loop of henle countercurrent
WebThe ultrastructural detail of the avian loop of Henle was examined, and comparisons were made to the loop of Henle of mammalian kidneys. Birds are the only group of vertebrates other than mammals that have the capability of elaborating a urine more concentrated than the plasma. Therefore, a comparis … Web8 de jun. de 2024 · Why loop of Henle is called countercurrent multiplier? The structure of the loop of Henle and associated peritubular capillary create a countercurrent multiplier system (Figure 25.6. 1). The countercurrent term comes from the fact that the descending and ascending loops are next to each other and their fluid flows in opposite directions …

Webcountercurrent mechanism provides a hyperosmotic concentrated urine; process of active NaCl reabsorption by the thick ascending lumb of the lop of Henle resulting in the generation of a hyperosmotic interstitual fluid in the outer and inner medulla when increased concentrations of ADH WebIt is the first segment of Henle’s loop. The descending loop is thinner than the ascending loop. It also has thick and thin segments like the ascending loop, but they are not distinguishable. The thinner portion of the limb is composed of simple squamous epithelium, and the thick portion is composed of simple cuboidal epithelium.
Web5 de jul. de 2010 · Henle’s Loop. An osmotic gradient is established and maintained by selective permeability in the loops of Henle (countercurrent multipliers) and passive diffusion in the vasa recta (countercurrent exchangers). This forms the basis for a countercurrent system, in which inflow runs parallel to, in intimate proximity with, and … WebIn 1951 Kuhn, Hargitay and Wirz showed experimentally that the loop of Henle was the most important part of the countercurrent multiplication system of urine-concentrating …
