Question
Why are frogs bellies soft and how much blood is needed to create one liter of urine?
Hi Jack: Two unrelated strange questions here. Why are frogs bellies soft? This is evolutionary biology and frogs as are they are because that is what works the best. Their skin is soft and slimy to protect them from drying out.
As for the urine question; it makes no sense since blood does not create urine. Blood carries the waste materials that pass out through the kidney. The amount of blood involved depends upon the kidney function.
