Vasodilation causes:.
Decreased pressure and decreased flow.
Decreased pressure and increased flow.
Increased pressure and increased flow.
Increased pressure and decreased flow.
The Correct Answer is B
Choice A rationale:
Vasodilation increases the diameter of blood vessels, which decreases resistance and thus decreases pressure. However, the increased diameter allows for increased blood flow, not decreased.
Choice B rationale:
Vasodilation decreases pressure due to the increased diameter of the blood vessels, and it increases flow because of the reduced resistance to blood flow.
Choice C rationale:
Vasodilation does not increase pressure; it decreases it.
Choice D rationale:
While vasodilation decreases pressure, it does not decrease flow; it increases it.
