The kidneys perform several important functions in the human body. One of these is to regulate the amount of water that makes up
the liquid part of blood. If too much water is present, the kidney will increase the amount of urine produced and lower the amount of liquid water in the blood. If the amount of water is too low, the kidney will decrease the amount of urine produced in order to conserve water. A person spends several days in a hot, dry desert environment with little water available to drink. Which statement BEST summarizes how the kidneys will function during this time? A) the amount of urine produced will increase to allow the body to eliminate heat B) the amount of urine produced will increase in order to eliminate waste products from the body C) the amount of urine produced will decrease in order to maintain the proper amount of water in the bloodstream D) the amount of urine produced will decrease because the body will not be producing waste products during this time
