WebKidneys produce urine by filtration: as blood passes through glomeruli, its thin walls (filter) permit water, salts, sugar, and urea (with other nitrogenous wastes as creatinine and uric acid). Walls also prevent late substances (proteins and blood cells) from filtering in the capsule. These stay in blood and normally do not appear in urine 5.
