And the first thing to notice about the loop of Henley is that it's located inside the medulla portion of the kidney. So recall that the medulla portion is the lower portion of the kidney, while the cortex is the upper portion. So the upper portion contains the glomerolus, the Bowman's capsule, the proximal and the distal convoluted tubule, while the medulla portion, this section of the kidney, contains our Loop of Henley as well as our collecting duct. Now, the second thing to notice about the loop of Henley is that around the Loop of Henley, it contains a network of blood vessels, a network of capillaries known as the vasarcta. And the vasarecta functions to absorb the electrolytes and nutrients that are reabsorbed from the loop of Henley and back into our body. Now, the final thing to notice about the loop of Henley is that we can divide the loop of Henley into three sections.
