Pulmonary Embolism

A blockage of one or more arteries in the lungs, usually caused by blood clots that travel to the lungs from a vein in another part of the body, most commonly the legs (called a deep vein thrombosis). The blood clot breaks off and travels to the lungs.

 *The pulmonary artery is the artery that carries deoxygenated blood from the heart to the lungs.
