Basically, a nephron comprises a renal tubule and blood vessels. The renal tubule expands into a cup-shaped structure called the Bowman's Capsule, which contains a ball of capillaries known as the Glomerulus. The Glomerulus is the primary structure of the filtering process.
The glomerulus filters blood and produces glomerular filtrate. This filtrate contains water, glucose [glucose: A simple sugar made by the body from food, which is used by cells to make energy in respiration.] , salts and urea [urea: A nitrogenous waste product resulting from the breakdown of proteins. It is excreted in urine.] .
