What is thrombi?

Thrombi are blood clots that form within blood vessels, obstructing normal blood flow. They can develop in arteries or veins and may lead to serious health issues, such as heart attacks or strokes when they block blood supply to vital organs. Thrombi can be composed of platelets, fibrin, red blood cells, and other components of blood. Their formation is often triggered by factors like injury to a blood vessel, slow blood flow, or changes in blood composition.
