Which term describes a traveling mass in the bloodstream that can cause obstruction?

• A. Embolus
• B. Embolism
• C. Thrombus
• D. Clot

Answer: (A)

A traveling mass in the bloodstream that can cause obstruction is called an embolus. It moves through the vessels and can lodge in a smaller vessel, cutting off blood flow. When this moving piece causes the blockage, the event is called an embolism. In contrast, a thrombus is a clot that forms in place on a vessel wall and stays there, and a clot is a general term for a coagulated mass that isn’t necessarily traveling. Embolus is the term that describes the traveling obstructing mass.
