An investigation was carried out to determine the effect of drinking excessive amounts of water on urine flow. urine was collected 3 times, at 10-minute intervals, from a subject. the subject then drank one liter of water at time marked zero. urine output was again measured every 10 minutes and the results were recorded in the graph below.

what effect might drinking two 32 ounce drinks have on a student?

a. the student would become dehydrated like drinking salt water
b. the student will need to urinate in one or two hours
c. the student will need to urinate immediately
d. the drinks will have no effect sine they are not pure water

The kidney filters potentially toxic substances in the blood, and thus “clears” the blood of those substances. this clearance function is dependent upon and proportional to the diffusion gradient of the substance across filtering capillaries, i.e. if the concentration of the substance is doubled, twice as much will be cleared from each ml of blood that is filtered. suppose that the body produces a constant amount of a substance x per unit of time. the kidneys eliminate substance x at a rate directly proportional to the concentration of the substance and the volume of blood cleared each minute (c): elimination = c × [x], where [x] is the steady-state concentration of substance x. imagine an individual with an initial concentration of x equal to [x]0 who develops kidney disease. her baseline clearance c0 drops to one half of the original (½c0). what is the new steady state concentration of x? (for simplicity, assume that substance x is 100% filtered by the kidney).
