Vertebrate urine production involves using the higher blood pressure to push water through a filter, along with water, small molecules pass into the filtrate (I). Then, cells and proteins are retained in the blood, and water is reabsorbed as the filtrate is passing through a long tube (II). Ammonia is not always the main waste product of metabolic breakdown for all vertebrates; some excrete urea or uric acid instead. Therefore, the statement (III) is not always true for all vertebrates.
