The aorta is the largest artery in the body. It carries blood to the abdomen, pelvis and legs. The aorta can sometimes become weak and start to enlarge. This is called an aneurysm. With early detection, the aneurysm can be treated before it becomes fatal.

The carotid arteries provide the main blood supply for the brain. Sometimes these arteries can narrow due to a buildup of plaque (a fatty substance). As the artery becomes narrower, your risk for a stroke becomes greater.

Arterial blockage can also develop in the arteries of the legs. This decreases the amount of blood flowing to the legs and can cause cramping, aching or a tired feeling in your legs while walking or exercising.
