Blood pressure increases when blood vessels constrict and their diameters decrease.

Question

Quizplus · Accepted Answer

Blood pressure is directly affected by the diameter of blood vessels. When blood vessels constrict and their diameter decreases, there is a smaller area for the blood to flow through, leading to increased pressure. Conversely, when blood vessels dilate and their diameter increases, there is a larger area for blood flow and decreased pressure.
