A clot formed within a vessel that remains in place is called what?

• A. Thrombus
• B. Embolus
• C. Plaque
• D. Aneurysm

Answer: (A)

A clot formed within a vessel that remains in place is called a thrombus. A thrombus adheres to the vessel wall and can block blood flow where it formed. It can result from factors like slow blood flow, injury to the vessel lining, or a tendency for blood to clot. If the clot breaks free and travels through the bloodstream to lodge elsewhere, that traveling clot is an embolus. Plaque refers to fatty buildup in the artery walls that narrows the lumen, not a clot. An aneurysm is a dilation or bulge in a vessel wall, not a clot.
