Question

multiple choice question
adh primarily promotes water retention, but at pathologically high concentrations it also acts as which of the following?

vasodilator

coagulator

vasoconstrictor

growth factor

Explanation:

ADH (Antidiuretic Hormone) primarily functions in water retention. At pathologically high concentrations, it acts as a vasoconstrictor, causing blood vessels to narrow, which can increase blood pressure. Vasodilators widen vessels, coagulators relate to blood clotting, and growth factors stimulate cell growth—none match ADH’s high - concentration effect.

Answer:

C. Vasoconstrictor
