noun, plural: thrombi
A thrombus is made from aggregates of platelets and fibrin that entrap cellular elements at the site where it forms. It remains at the site where it may cause thrombosis. In larger blood vessels, the thrombus may hinder blood flow. However, in smaller vessels, it may occlude blood flow, resulting in the death of the affected tissue.
Word origin: Greek thrombos (clot)
- embolus (pathology)
