Question

Quizplus · Accepted Answer

The amount of fluid passing through a blockage in an artery (or any tube) is proportional to the fourth power of the diameter of the opening, according to the Hagen-Poiseuille equation. This means that even a small decrease in the diameter due to blockage can lead to a significant reduction in blood flow.
