Blood Clot in Motion

A blood clot in the wall of an artery can break off and travel through the bloodstream (becoming an embolus). The embolus may then lodge in an artery that supplies blood to the brain and block blood flow there. When fatty deposits (shown in yellow) due to atherosclerosis have narrowed an artery, an embolus is more likely to block the artery.
