Question

multiple choice question
if a tissue is inadequately perfused, autoregulation causes which of the following?
vasoconstriction
vasodilation

Explanation:

In the context of tissue perfusion and autoregulation (a concept in physiology, part of Biology), when a tissue is inadequately perfused (not getting enough blood flow), autoregulation mechanisms aim to increase blood flow to the tissue. Vasodilation is the widening of blood vessels, which increases blood flow, while vasoconstriction would decrease it. So to improve perfusion, autoregulation causes vasodilation.

Answer:

Vasodilation
