Answer;
The above statement is true
Urination is one of the key mechanisms for losing fluid from the human body
Step-by-step explanation;
-The body's homeostatic control mechanisms ensure that a balance between fluid gain and fluid loss is maintained. Water or fluid loss from the body is undertaken by several mechanisms which mainly include urination and sweating. Others include; respiration and through digestive tract.
-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. Normally, little water is lost from the digestive tract.
