This stock medical exhibit features a silhouette of a male with the major veins, heat, lung, and brain visible beneath the skin. It describes the mechanism of a pulmonary embolism, in which an embolus breaks free from a clot in the right leg and travels up the venous system into the heart and lungs. A second image is a more detailed view of the heart, lungs, and brain. This image shows the large clot forming in the pulmonary arteries and cutting off the flow of blood to the lungs, leading to hypoxia of the brain and eventual death. |
