10 Things You Need to Know About Blood Clots

3. Types of Blood Clots

There are three primary types of blood clots that can form: superficial venous thrombosis, deep-vein thrombosis (DVT), and pulmonary embolism. The main difference between the first two (the thromboses) and the latter, is that thrombus blood clots tend to be stationary and block blood flow, while embolism blood clots tend to break loose and travel to other parts of the body (i.e. very dangerous). Blood clots can also be categorized by where they form. The most common are arterial, which are equally bad because they can block oxygen from reaching organs and tissues.
