Atherosclerosis impedes coronary blood flow by which of the following mechanisms? *1 pointA. Plaques obstruct the veinB. Plaques obstruct the arteryC. Blood clots form outside the vessel wallD. Hardened vessels dilate to allow the blood to flow through

An atherosclerotic plaque results in two key changes to the vessel, including:Group of answer choicesHardening (higher compliance) of the vessel wall.Narrowing of the vessel lumen (reduced radius and increased resistance to blood flow).Hardening (lower compliance) of the vessel wall.Narrowing of the vessel lumen (increased radius and decreased resistance to blood flow).
