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.
Each kidney has many millions of nephrons. The glomerulus filters blood and produces glomerular filtrate. This filtrate contains water, glucose, salts and urea. Large molecules such as protein are too large to fit through the blood capillary walls.The bowman's capsule collects the filtrate and it enters the tubules.All glucose is reabsorbed immediately into the blood capillaries.his filtrate contains water, glucose, salts and urea.
