Obstruction of a vessel by a blood clot is known as which medical condition?

Explanation:
When a clot forms inside a vessel and blocks the flow, that is thrombosis. A thrombus develops in place and narrows or stops blood passage, often due to factors that promote clotting, changes in blood flow, or vessel wall injury. If the blockage were caused by a traveling clot that moved from another site, that would be an embolism, not thrombosis. An aneurysm is a dilated portion of a vessel, and hemorrhage is active bleeding, not a clot-caused obstruction. So the term that best fits obstruction by a clot forming within the vessel is thrombosis.
