What is an embolus in medical terminology?

An embolus refers specifically to a substance, commonly a blood clot, that travels through the bloodstream and can obstruct blood vessels in different parts of the body. This is a critical concept in understanding certain medical conditions, particularly those related to cardiovascular health. When a blood clot forms in one area, it can detach and move through the circulatory system, leading to serious complications such as a stroke or pulmonary embolism, depending on where it ultimately lodges.

The recognition of an embolus is vital for medical professionals as it allows them to assess the potential risks and necessary interventions to prevent severe outcomes. Understanding this definition helps to clarify the role of emboli in various health scenarios, emphasizing the importance of quick diagnosis and treatment in cases where emboli may pose a threat to circulation and overall health.
