Compare the terms concentric and eccentric. Why do you think eccentric plaque causes turbulence?

What will be an ideal response?

Concentric refers to circles within circles, or in the case of plaque, circular layers that build upon each other, eventually narrowing the diameter of the vessel lumen. Eccentric describes a less predictable pattern of accumulation. Blood flowing through concentric plaque still moves more or less in a straight line. Blood moving through an artery with eccentric plaque does not move in a straight line. Pockets formed by irregularly shaped outcroppings of plaque cause the blood to change directions, resulting in swirls and turbulence.
