Causes of Clogged Arteries. There are many substances and properties that can circulate with the blood, including cholesterol, calcium, fat, fibrin and cellular waste. When these substances accumulate on the inner walls of the arteries, they turn into plaque buildup.
In some cases, plaques can break or rupture. As a result, blood cells called platelets will try to repair the artery, forming a blood clot. Like gunk in a clogged drainpipe, this buildup prevents a free flow of blood through the arteries. Blood carries oxygen and nutrients to the heart.
