Which outcome occurs when a blood vessel undergoes stenosis?

A)Elevated blood flow velocity locally✓

B)Decreased shear stress at stenosis

C)Reduced overall arterial blood volume

D)Lowered distal blood pressure chronically

💡 Explanation

The local blood flow velocity increases because the *continuity equation* dictates that volumetric flow rate remains constant through narrowing; therefore, velocity must increase at stenosis, rather than decreases in flow or pressure.
