Smoking and Heart Disease Risk. Smoking is a major risk factor for coronary heart disease, a condition in which plaque builds up inside the coronary arteries. Thesearteries supply your heart muscle with oxygen-rich blood. When plaque builds up in the arteries, the condition is called atherosclerosis.

Answer 2

Explanation:

Smoking limits blood flow through your arteries and veins in two main ways. First, nicotine, the most addictive chemical in cigarettes, causes your blood vessels to get more narrow. This both limits the amount of blood they can carry and, over time, causes them to lose their flexibility and become more stiff.
