Quizplus · Accepted Answer

An aneurysm is a blood-filled pocket that bulges out from a weak spot in an artery wall. This can be dangerous as it can rupture and cause severe bleeding. A thrombus is a blood clot that forms inside a blood vessel, whereas an embolism is a blood clot that has broken off and traveled to another part of the body. Fibrillation refers to irregular and uncoordinated contractions of the heart muscles.
