What is the definition of an embolism?

An embolism is defined as a piece of a blood clot (or other debris) that has detached from its original site and travels through the bloodstream to a different location, where it can obstruct blood flow. This blockage can lead to serious health issues, such as a stroke or a heart attack, depending on where in the body the embolism occurs. The mobility of the embolus is what distinguishes it from a thrombus, which is a stationary blood clot that remains in place. Understanding this definition is crucial, as it highlights the potential dangers of embolisms and their role in vascular health complications.
