How does an artery become blocked? Blockage occurs when the artery becomes so narrow that blood can no longer get through or, more commonly, when something traveling through the blood becomes lodged in the narrowed artery. This is often a blood clot but can also be a piece of plaque that broke off.
Why is it important to have healthy arteries? Healthy arteries allow blood to flow freely through the body, feeding vital organs such as the heart and brain, with oxygen and nutrients. This allows for better physical and mental functioning and a reduced risk of heart attack and stroke.
