Example Question #173 : Systems Physiology
Which of the following functions does antidiuretic hormone (ADH) serve?
Possible Answers:
None of these
Decreases water volume in the urine
Induces vasoconstriction and increases blood pressure
All of the choices
Increases water permeability of the collecting ducts
Correct answer:
All of the choices
Explanation:
ADH is a hormone that increases permeability to water in the collecting ducts and therefore increases water reabsorption from the urine. This decreases the volume of water in the urine. Additionally, it can induce vasoconstriction in high concentrations, which narrows blood vessels and thereby increasing blood pressure.
