What Is Carotid Artery Disease?
Arteries are the blood vessels that circulate blood from the heart to the rest of your body. Carotid arteries, two blood vessels in your neck, have the critical job of bringing blood to the brain. Over time, substances in your blood build up on your artery walls, leaving behind a waxy plaque. As this plaque accumulates, it hardens and narrows your arteries. Narrowed arteries affect blood flow to the brain and other parts of the body.
