What term describes a clot formed by a substance that has detached from another location?

The appropriate term for a clot that has formed from a substance that has detached from its original location is embolus. An embolus refers specifically to a portion of a clot, fat, air, or other material that travels through the bloodstream and lodges in a vessel, which can lead to serious complications, such as occlusion of blood flow to tissues. In contrast, a thrombus is a clot that forms at the site of origin and remains attached to the vessel wall. An aneurysm is an abnormal bulging or dilation of a blood vessel wall, while hemorrhage refers to bleeding, either internally or externally. Understanding the differences between these terms is important in the context of vascular health and interventions.
