What determines the amount of water reabsorbed during the formation of urine in human kidneys?
The amount of excess water and dissolved waste the human body must remove
In the nephron, the glomerulus filters a large volume of fluid; most of the water is then reabsorbed in the tubules.
How much water is reabsorbed is adjusted to the body’s needs: when the body has excess water to remove, less is reabsorbed and dilute urine is formed; when water must be conserved, antidiuretic hormone (ADH) increases reabsorption and concentrated urine is formed.
Kidney size, the type of food eaten or blood oxygen level do not directly set the amount of water reabsorbed.
Hence, The amount of excess water and dissolved waste the human body must remove.
