What is the difference between septic embolisms in the lungs and a pulmonary embolism?

Bacteria: Emboli are stuff (most commonly clots) that move from somewhere to somewhere else down a blood vessel, in this case from clots in veins of the body, down to the heart, and through its right side to the lungs, where they can block blood flow to these organs. Septic emboli are stuff that also has bacteria inside, and therefore can cause further infection in the lungs, and even greater damage.
