Which term means stationary blood clot?

• A. Embolism
• B. Thrombus
• C. Thrombosis
• D. Thrombolytic

Answer: (B)

A thrombus is a stationary blood clot that forms within a vessel or the heart. It stays at the site of formation and can block blood flow as it grows. In contrast, an embolism involves a clot or other material that breaks loose and travels through the bloodstream to lodge elsewhere. Thrombosis is the process of forming a clot, while a thrombolytic is a drug that dissolves clots. Because the question asks for the term meaning a clot that stays in place, the correct term is thrombus.
