If you are eating and inhale something like spaghetti sauce? how would your lungs get rid of the foreign substance?

Cough and swallow: So first your lungs and bronchi try to expel it by coughing 'your lungs out.' in all seriousness this gets rid of quite a lot of the toxic substances. If you cannot cough it out something must take it out or someone helps you like patting on back etc. After that whatever is left is engulfed by the natural killer cells in the lungs. These break down the particles by surrounding them and expelng.
