Verified step by step guidance
1
Understand the role of the autonomic nervous system (ANS) in regulating involuntary body functions, including heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal.
Recognize that vasoconstriction and vasodilation are processes controlled by the ANS that affect the diameter of blood vessels.
Vasoconstriction refers to the narrowing of blood vessels, which increases blood pressure by reducing the space through which blood can flow.
Vasodilation refers to the widening of blood vessels, which decreases blood pressure by increasing the space through which blood can flow.
Connect these processes to the regulation of blood pressure, as vasoconstriction and vasodilation directly influence blood pressure levels, which is a primary function of the ANS.
