उत्तर
The composition of glomerular filtrate and urine is not the same because glomerular filtrate contains water, glucose, amino acids, salts, urea, and other small molecules, whereas urine mainly contains water, urea, uric acid, and salts. During the process of urine formation, useful substances like glucose, amino acids, and most water are reabsorbed into the blood, and additional wastes are secreted into the tubule. Therefore, the final urine is more concentrated and contains only waste products, making its composition different from glomerular filtrate.
