where do blood clots in the lungs come from
When a blood clot builds up in a vein, a condition called DVT, part of it can break off and float in your bloodstream. It travels from deep veins, usually in your leg, through veins in your belly and into your heart. From there, blood goes to your lungs. But if the clot goes with it, it can get stuck and block the blood vessels. This condition, called pulmonary embolism, is very serious. It can permanently damage a part of your lung. If a clot is large or if there are many clots, pulmonary embolism can even be deadly.
