Answer: Ok so this may be a little off but ill do my best
Step-by-step explanation:
On a typical day, the average adult will take in about 2500 mL (almost 3 quarts) of aqueous fluids. Although most of the intake comes through the digestive tract, about 230 mL (8 ounces) per day is generated metabolically, in the last steps of aerobic respiration. Additionally, each day about the same volume (2500 mL) of water leaves the body by different routes; most of this lost water is removed as urine. The kidneys also can adjust blood volume though mechanisms that draw water out of the filtrate and urine. The kidneys can regulate water levels in the body; they conserve water if you are dehydrated, and they can make urine more dilute to expel excess water if necessary. Water is lost through the skin through evaporation from the skin surface without overt sweating and from air expelled from the lungs. This type of water loss is called insensible water loss because a person is usually unaware of it.ADH is a hormone in your body that helps your kidneys manage the amount of water in your body. Dehydration means you need water and when your thirsty your body wants water. So when your thirsty, your brain is letting you know you need water, and if you don't drink water you will become dehydrated and that can lead to kidney failure.
Your kidneys have a very important role of water management.
I really hope this helps :)
