In the arterial disease atherosclerosis

A. plaque accumulates on the interior walls of arteries.
B. blood flow through affected arteries slows.
C. risk of a thrombus or embolus forming increases.
D. all of the above may happen.

Answer 1

In atherosclerosis, plaque accumulates on the interior walls of arteries, slowing blood flow and increasing the risk of clot formation. All of these outcomes may happen.

Step-by-step explanation:

In the arterial disease atherosclerosis:

1. Plaque accumulates on the interior walls of arteries. This occurs when cell debris, cholesterol, and other substances build up inside the arteries, narrowing them and reducing blood flow.
2. Blood flow through affected arteries slows down. As the plaque builds up, it stiffens and narrows the artery, further decreasing the flow of blood.
3. Risk of a thrombus or embolus forming increases. Plaque can rupture or become detached from an arterial wall, causing blood clots that can block arteries or travel to other parts of the body.
4. All of the above may happen. Atherosclerosis can have multiple effects on the arteries and their functioning.
