WebTubular secretion also removes excessive potas-sium from the body. Nearly all potassium ions in the filtrate are reabsorbed in the proximal convoluted tubule and ascending nephron loop. Therefore, almost all potassium in the urine is derived from active tubu-lar secretion into the last portions of the distal con-voluted tubule and collecting ducts. 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.
