WebEach nephron begins with a filtration component that filters the blood entering the kidney. This filtrate then flows along the length of the nephron, which is a tubular structure lined by a single layer of specialized cells and surrounded by capillaries. WebTubular secretion occurs throughout the different parts of the nephron, from the proximal convoluted tubule to the collecting duct at the end of the nephron. Hydrogen Ion Secretion The tubular secretion of H+ and NH 4 + from the blood into the tubular fluid is involved in blood pH regulation.
