← ScienceWhich outcome occurs when blood flow sharply increases in a coronary artery stenosis?
A)Increased risk of boundary layer separation✓
B)Laminar flow profile stabilization
C)Decreased intimal plaque deposition rate
D)Reduced endothelial cell permeability
💡 Explanation
Increased blood flow through a stenotic artery raises the Reynolds number, promoting turbulent flow and therefore the increased risk of boundary layer separation at the stenosis site because the inertial forces dominate over viscous forces; rather than stabilization.
