About Body Water The body loses water primarily by excreting it in urine from the kidneys. Depending on the body's needs, the kidneys may excrete less than a pint or up to several gallons of urine a day. About 1½ pints (a little less than a liter) of water are lost daily when water evaporates from the skin and is breathed out by the lungs. Profuse sweating—which may be caused by vigorous exercise, hot weather, or a high body temperature—can dramatically increase the amount of water lost through evaporation.

The rest is found in the extracellular space, which consists of the blood vessels (intravascular space) and the spaces between cells (interstitial space). Dehydration occurs when the amount of water leaving the body is greater than the amount being taken in. The body is very dynamic and always changing.
