In the molluscs, an initial fluid is formed in the kidney by ultrafiltration of the blood through the wall of the heart. Reabsorption of valuable materials hke glucose and secretion of unwanted compounds occur subsequently resulting in the formation of the final urine.

Hydrostatic pressure of the blood provides the filtration pressure and application of back pressure stops urine production.
