Question

How does cholesterol block an artery?

Answer 1

It builds up with plaque which cuts off the rich blood flow.

Explanation:

Cholesterol travels through the bloodstream as something we call "plaque."

This plaque is not considered too harmful unless you have too much of it.

When there's too much plaque, it bloats up and cuts off the rich blood flow in the heart.

Some of this blood flow goes to the arteries (since we know that arteries contain the rich blood), but when the plaque buildup blocks the flow of blood and thus it is harder to get through to the arteries.
