                     Define














                      Blockage of the pulmonary artery (or one of its branches).






                      Venous thrombosis (a blood clot in a vein) moves from its place of

                          formation to the arteries in the lungs. Most blood clots come from the
                          pelvic veins, abdominal veins and venous thrombus in the femoral. This

                          process is called thromboembolation.






                      In addition to blood clots, pulmonary embolism can also occur as a result

                          of fat or bone (associated with injury signalling), air (during diving), tumour
                          cell clotting, and amniotic fluid (during childbirth).
