===Thromboembolism===
Virchow is also known for elucidating the mechanism of pulmonary [[thromboembolism]] (a condition of blood clotting in the blood vessels), coining the terms [[embolism]] and [[thrombosis]].<ref>{{cite journal|last1=Kumar|first1=D.

This gives rise to the very frequent process on which I have bestowed the name of Embolia."<ref>{{cite book|last1=Murray|first1=T.

He then proceeded to prove this hypothesis by well-designed experiments, repeated numerous times to consolidate evidence, and with meticulously detailed methodology. This work rebutted a claim made by the eminent French pathologist [[Jean Cruveilhier]] that [[phlebitis]] led to clot development and that thus coagulation was the main consequence of venous inflammation. This was a view held by many before Virchow's work. Related to this research, Virchow described the factors contributing to venous thrombosis, [[Virchow's triad]].<ref name="Bagot2008" /><ref>{{cite book|last1=Dalen|first1=James E.|title=Venous Thromboembolism|year=2003|publisher=Marcel Decker, Inc.|location=New York|isbn=978-0-8247-5645-1|url=https://books.google.com/books?id=u-3Fiw7yE5kC}}</ref>
