Explanation:
The answer is ultrafiltration. This is helped by the hydrostatic pressure and blood pressure in afferent renal arteriole. Molecules such as water, glucose, urea, sodium chloride, amino acids pass through the semipermeable membrane of the dense capillary network of the glomerulus to form glomerular filtrate. Some of these molecules are later reabsorbed in the renal tubules.
i think the answer is because the cell membrane acts as a protecter for cells. It also moves liquds and since it does move liquids it wouldn't desolve from it.
