ELI5: Throughout our lives, how much food goes into our lungs and how is it disposed of?

Hopefully not very much at all. If food were to make it all the way into the lungs your body would attempt to violently remove it via coughing. Particles that couldn't be removed that way would slowly be pushed out of the lungs by tiny hairs called "cilia". Millions of those tiny flapping tendrils create a flow of mucus up and out of the lungs to be coughed up.
