In this lesson we will see about the process of filtration of kidneys.  Kidneys manufacture urine by a process called filtration. Each microscopic glomerulus wall is thin enough to allow water, sugar, salt, urea, and other nitrogenous wastes like uric acid and creatinine to go away the bloodstream. These materials going away from each glomerulus are accumulated in a minuscule cup-like structure called Bowman's capsule, which encloses each glomerulus. The walls of the glomeruli check large substances like proteins and blood cells from filtering into the Bowman's capsules. These substances stay behind in the blood and normally do not come into view in urine. Renal tubule is a long twisted tube attached to the Bowman's capsule. These tubules are covered by tiny capillaries. When the water, sugar, urea, salts and other nitrogenous wastes pass through these renal tubules, all of the sugar and most of the water and some salts go again to the bloodstream. This process is ...
