If the diameter of a blood vessel decreases due to atherosclerosis, which consequence follows regarding blood flow and pressure?

💡 Explanation

When vessel diameter decreases, resistance to flow increases. Because the body attempts to maintain constant blood pressure, decreased vessel diameter increases resistance, and therefore blood pressure rises while flow decreases, rather than either remaining constant or increasing.
