Question

The composition of glomerular filtrate and urine is not same. Comment.

Answer 1

The composition of glomerular filtrate and urine is not the same as the glomerular filtrate contains a large amount of water and other dissolved substances such as urea, uric acid, creatinine, amino-acid, glucose, sodium, potassium, vitamins etc.
Urine, on the other hand, is a transparent light yellow fluid, which is formed after rigorous reabsorption and secretion from the filtrate. It constitutes about 95% water and 5% of other organic and inorganic substances.
Organic substances in urine include nitrogen, urea, ammonia uric acid, hormones and enzymes.
Whereas inorganic substances in urine includes chloride, phosphate and other ions. Glucose is not found in urine normally. Hence, the composition of glomerular filtrate and urine is different.
