Question

Vasoconstriction causes:

• A. Increase in heart beat
• B. Decrease in heart beat
• C. Increase in blood pressure
• D. Decrease in blood pressure

Answer 1

The correct option is C Increase in blood pressure

Vasoconstriction is the narrowing of the blood vessels resulting from contraction of the muscular wall of the vessels, in particular the large arteries and small arterioles. When blood vessels constrict, the flow of blood is restricted or decreased, thus increasing vascular resistance causing a reduction in blood flow. Thus, vasoconstriction usually results in an increase in systemic blood pressure.
