Overview

Each glomerulus (microscopic "filtering screen") has a tubule that transports urine to the ureters (see anatomy) and metabolically alters the urine and its chemicals. Because the tubules are exceedingly metabolically active, they are very dependent on the oxygen that supplies the tubular cells. They are often described as being nearly oxygen starved because they work so hard. Close to 200 liters of fluid is filtered across the glomeruli, and the tubules reabsorb 99% (198 liters) o...Read the full article
