The Difference Between a Thrombus and an Embolus is Whether

Question

The difference between a thrombus and an embolus is whether it is moving.

Accepted Answer

A thrombus is a blood clot that forms within a blood vessel and remains in place, while an embolus is a blood clot or other material (such as air or fat) that breaks off from its original site and moves through the bloodstream to another location. Therefore, the key difference between the two is that a thrombus is stationary, while an embolus is moving.
