Fig. 5.6 SEM images of a colon tissue affected by cancer. A myriad of micron-sized and
nanoparticles are visible. They are silicates (b) and stainless-steel (d)
reasons, no efficient defense mechanisms are available to the subject. In those
cases, a thrombus forms without originating at and being attached to the vascular
wall as usually happens. So, being free to float, it necessarily migrates along the
veins—if the phenomenon has taken place in the venous system—to reach the lung
circulation and be the cause of pulmonary thromboembolism. In case all that occurs
in the arteries, the outcome can be a stroke or a myocardial infarction. It is only
