What is a moving blood clot transported in the blood stream called?

A moving blood clot transported in the bloodstream is called an embolus. When a clot forms in one location and travels through the bloodstream to another part of the body, it can lead to serious complications, such as a blockage in blood vessels, which may result in conditions like a stroke or pulmonary embolism. If the embolus becomes lodged in a blood vessel, it can disrupt blood flow and damage tissues.
