The urine should be produced that comprise of 95% water and 5% should be considered as the nitrogenous wastes.

Here the water should be excreted arise from the human body that should be in the form of urine. The kidney should played the major role for the excretion process. Here the normal human urine involved 95 percent water and 5 percent solid wastes.

The urine should be formed via applying 3 steps:

Glomerular filtration: Glomerular filtration arise in the glomerulus at the time when blood is filtered.
