A tuft of capillaries situated within a Bowman's capsule at the end of a renal tubule in the vertebrate kidney that filters waste products from the blood and thus initiates urine formation. The main function of glomeruli is to clean the blood. 2) The substances that normally pass through glomerular walls are small molecules such as water, inorganic salts, amino acids, protein hormones, glucose, fructose, sodium, potassium, calcium, and chloride. Blood cells and proteins are too large to penetrate the glomerular walls and return to the general circulation. 3) Blood cell casts are of prime clinical significance. Even a rare finding is indicative of renal "glomerular" bleeding. This finding can obsolete the need for invasive urologic tests to determine the origin of the hematuria.
