Final answer:
The ANS is responsible for both vasodilation and vasoconstriction. (False)
Step-by-step explanation:
False. The autonomic nervous system (ANS) is responsible for regulating involuntary bodily functions, including vasodilation and vasoconstriction. Vasodilation refers to the widening of blood vessels, which leads to increased blood flow, while vasoconstriction refers to the narrowing of blood vessels, which reduces blood flow. These processes are regulated by different branches of the ANS: vasodilation is primarily mediated by the parasympathetic division, while vasoconstriction is primarily mediated by the sympathetic division.
