A thrombus is defined as what?

A thrombus is defined as what?

• A. A traveling clot that forms and moves through vessels
• B. A stationary blood clot that forms in a vessel
• C. An infection in the bloodstream
• D. A rupture of a blood vessel

Answer: (B)

A thrombus is a stationary blood clot that forms in a vessel and adheres to the vessel wall. It develops in place as part of the coagulation process and can obstruct blood flow, leading to ischemia in the supplied tissues. This is different from an embolus, which is a fragment of clot or other material that travels through the bloodstream to lodge elsewhere. The other options describe different problems: an infection in the bloodstream is septicemia, and a rupture of a blood vessel leads to hemorrhage.
