A. One of you per group will be on his/her normal fluid intake for 24 hours prior to ingesting the test volume of water [normal hydration - water loaded). B. One of you per group will be on his/her normal fluid intake for 24 hours prior to ingesting the test volume of 0.9% NaC1 [normal hydration - saline loaded]. C. One of you per group will be over-hydrated by drinking 2 ml of tap water per kilogram body weight per hour in addition to your normal fluid intake during the previous 24 hours (awake) before ingesting the test volume of water in lab [over-hydration - water loaded]. D. One of you per group before drinking a test volume load of water will be partially dehydrated by abstaining from fluids during the previous 24 hours, except for one cup of coffee, tea, milk or soft drink at the evening meal and at breakfast. No additional fluids should be taken up to the time of the experiment. Breakfast and lunch can be eaten but they should be low in protein [dehydrated, water loaded). Question: For each condition A-D outlined, what do the data suggest and what do you predict will happen to: Urine volume Urine flow specific gravity [Na+] in the urine
