Answer to Question 1

ANS: A
The kidneys maintain the volume and composition of body fluids by two related mechanisms. First, filtration and reabsorption of sodium adjust urinary sodium excretion to match changes in dietary intake. Second, water excretion is regulated by secretion of antidiuretic hormone (ADH or vasopressin).

Answer to Question 2

ANS: D
Extracellular water is found in three subcompartments: (1) intravascular water (plasma), (2) inter-stitial water, and (3) transcellular fluid. Intravascular water makes up approximately 5 of the body weight. Interstitial water is water in the tissues between the cells. It makes up approxi-mately 15 of the body weight. Transcellular fluid is quite small in proportion to plasma and in-terstitial fluid.
