How are blood clots formed?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)
A blood clot, also known as a thrombus, is formed when particles in your blood combine to form a solid piece of matter. A blood clot usually consists of platelets, fibrin, and other components. They usually form for your benefit -- to stop bleeding after a cut or scrape. However, blood clots can form in situations that don’t involve a cut at all. Long periods of inactivity or damage to an arterial wall can also form a clot. An embolus is a traveling, broken-off piece of a thrombus. As it travels, it eventually degrades. However, if it travels through a more narrow passageway and gets stuck, the consequences can be deadly.
