What is the definition of a thrombus?

Blood clot
Blood vessel inflammation
Platelet aggregation
Blood loss

The correct answer is: Blood clot

A thrombus refers specifically to a blood clot that forms in a blood vessel, effectively obstructing the flow of blood. This can occur in arteries or veins and is typically made up of aggregated platelets, fibrin, and various blood cells. Understanding this definition is crucial for recognizing the clinical significance of thrombi, which can lead to serious conditions such as heart attacks or strokes if they obstruct blood flow to vital organs. The other terms are related to different health conditions: inflammation of blood vessels, accumulation of platelets without clot formation, and the state of losing blood, none of which accurately capture the essence of a thrombus.
