In all humans, urine originates in the kidney and is discharged through the urethra. Water, urea, salts and pigments form the urine in our body. More water is expected to be excreted where the amount of dissolved waste is higher in the body. As a consequence, the quantity of urine output is increasing. Urine produced also depends on the antidiuretic hormone (ADH) and the habitat of the body. Urine formation in our body is primarily conducted in three steps, namely glomerular filtration, reabsorption and secretion. 

The total volume of urine released in humans is controlled by the presence of the total amount of water, the total amount of nitrogen compounds dissolved in the urine, some hormones that help to monitor the flow of water and sodium ions into and out of the nephrons. The total amount of urine generated is thus in direct balance to the volume of fluid and other nitrogen waste.
