Webb22 nov. 2024 · The loop of Henle has four segments that differ in their lining epithelium and the degree of permeability to water, salts, and urea. These are: 1. The thick descending limb: it is a straight continuation of the proximal convoluted tubule to enter the medulla with a lining epithelium nearly similar to that of proximal convoluted tubules. 2. & 3. WebbThese nephrons are called cortical nephrons. About 15 percent of nephrons have very long loops of Henle that extend deep into the medulla and are called juxtamedullary nephrons. Blood exits the glomerulus into the efferent arteriole ( Figure 25.2.1 ). The efferent arteriole then forms a second capillary network around the tubule, called the ...
