Changes in arterial diameter impact blood pressure; vasoconstriction raises it, whereas vasodilation lowers it.
Variations in arterial diameter affect blood pressure: vasoconstriction increases it, while vasodilation decreases it.

| Back | Vasoconstriction increases the blood pressure (more resistance). Vasodilation decreases the blood pressure (less resistance). |
