This 3D medical animation depicting Deep Vein Thrombosis (DVT or Deep Venous Thrombosis) begins by showing a blood clot forming in a lower leg vein. As red blood cells flow through the vein, slower moving cells and other blood elements accumulate on the venous valves, creating a stationary blood clot, or thrombus, blocking the blood flow in the vein. When the thrombus breaks free of the valve leaflet, it is then called an embolus, and travels toward the heart and lungs. The last section of the animation shows the embolus lodging in the lung tissue to form a potentially life-threatening pulmonary embolism.
