WebLoop of Henle or nephron loop in the kidney is a tubule that opens from the proximal convoluted tubule (PCT) and leads to the distal convoluted tubule. Its vital role is to produce a concentration gradient in the kidney and help in the filtration process. Its structure is composed of a thin descending loop and an ascending loop.
