foreign body

Something lodged inside

A foreign body is an object or substance that doesn't belong where it's found—typically something lodged in living tissue or a bodily cavity.

Doctors remove foreign bodies from eyes, ears, and wounds: The X-ray showed a foreign body in her lung.

The term extends to any unwanted intrusion in a system or environment.
